- —Dudley's farewell to his cousin Harry Potter[src]
Dudley Dursley (born 23 June, 1980) was the Muggle son of Vernon and Petunia Dursley and cousin of Harry Potter. He was obese and insolent as a result of his parents spoiling him throughout his childhood, although he became muscular in his teens. He and his gang often tormented Harry, taking after the example set by his parents, as well as other weaker and younger children in their neighbourhood and at school.
In 1995, he faced Dementors for the first time and was saved by Harry, after which he mellowed and became generally kinder to his cousin. He left 4 Privet Drive in 1997, along with his parents, to be hidden and protected themselves from becoming the next victims of Lord Voldemort and his Death Eaters by the Killing Curse, under the protection of the Order of the Phoenix.

On 1 November, 1981, Dudley had a tantrum when Vernon was going to work. He physically abused Petunia when they went out, demanding she provide him with sweets, something that was witnessed by Minerva McGonagall in her Animagus form. Hours later, Harry was delivered to the Dursleys after the attack on the Potters in Godric's Hollow. Over the following few weeks, Dudley took to prodding and pinching Harry.
In June 1985, his Aunt Marge was at Privet Drive to attend Dudley's fifth birthday party. She whacked Harry Potter, then four years old, around the shins with her walking stick to stop him from beating Dudley at musical statues.
During their years together at St. Grogory's Primary School, Dudley frequently chose Harry as his favourite punching bag with the help of Dudley's Gang. Because of the pair's differing sizes, Dudley could easily hurt Harry, although Harry was often faster than Dudley.
Aunt Marge was present again at Dudley's tenth birthday party when Harry was nine. Harry accidentally stepped on Ripper's paw, causing the dog to chase Harry out into the garden and up a tree, while Dudley laughed himself silly. Marge refused to call the dog off until past midnight, much to the Dursleys' delight.
Summer of 1991
Eleventh birthday party
- "Thirty-six. That's two less than last year!"
- —Dudley's tantrum on his eleventh birthday[src]
Dudley celebrated his eleventh birthday on 23 June, 1991. His presents included a new computer, a second television, a remote control aeroplane, sixteen new computer games, a gold wristwatch, a video recorder, a cine-camera, a remote control crane, a racing bicycle, (which Harry found odd, as Dudley was very fat and hated exercise if it did not include punching someone) and more. When Dudley counted his presents, he got angry and claimed that he had two fewer than his last birthday, although he actually had one fewer than his last birthday. Petunia promised that when the family went out, she would buy him two more presents, and satisfied with this, he did not throw a tantrum.
The Vanishing Glass
When Mrs Figg called the Dursleys to tell them she could not take Harry for the day because she had broken her leg, Dudley was horrified. While Vernon and Petunia decided what to do with Harry, Dudley pretended to cry, playing on his mother's habit of giving him whatever he wanted. In between "sobs", Dudley commented that he did not want Harry to spoil his birthday by tagging along: when his mother was not looking, he shot Harry a nasty grin. When his friend Piers Polkiss arrived, he ceased his act immediately.
With no other option, the Dursleys reluctantly took Harry with them to the zoo for Dudley's birthday (even after Dudley's fit as they could not legally leave him home alone). At the entrance, his parents bought him and Piers large chocolate ice creams. Before they could hurry off, the saleswoman asked Harry what he would like, then Vernon and Petunia were forced to buy Harry a cheap lemon ice lolly, although he seemed to like it regardless. At lunch time, Dudley had a temper tantrum because his knickerbocker glory was not big enough, as there was "not enough" ice cream on it: his father bought him another one and Harry was allowed to finish the first one though only because it would be a huge waste to throw out.
After lunch, the group visited the reptile house and Dudley quickly found the largest snake in the place which was a sleeping boa constrictor. Dudley pressed his nose against the glass and asked his father to make the snake wake up. After much rapping on the glass, it made no movements at all and Dudley walked away, easily bored. A few moments later, Piers drew Dudley's attention back to the snake when he saw Harry talking to it. Waddling over, Dudley quickly shoved Harry out of the way and onto the ground. Within a few moments, Dudley found the protective glass gone and he and Piers jumped backwards in shock. As the snake uncoiled itself and slithered off, Dudley and Piers ran away, screaming. Harry had managed to do this with underage magic, although he thought it had been an accidental misunderstanding at the time. Piers tattled on Harry saying that he had seen him talking to the snake. In the car on the way home, Dudley claimed that the snake had nearly bitten his leg off. Harry, on the other hand, only saw the snake playfully snapping at Dudley's heel as it went past.
Discovery of the wizarding world
- "Who on earth wants to talk to you this badly?"
- —Dudley, amazed about the number of letters sent to Harry[src]
By the time the summer holidays had begun, Dudley had broken his video camera, crashed the remote-controlled aeroplane, and knocked an already injured Mrs Figg over with his racing bike. Near the beginning of July, Dudley was accepted into Smeltings Academy, his father's alma mater. After returning from London with his new school uniform, Dudley paraded around the house in the get-up, which included a maroon tailcoat, orange knickerbockers, a boater, and a knobbly stick. He took to whacking everyone and everything within reach with this stick, which became extremely annoying to Harry.
The following morning when the post arrived, Dudley alerted his father that Harry had received a letter. Seeing his parents' reactions to the letter's contents, Dudley demanded to see it. Not used to being ignored, Dudley rapped his father on the head with his Smelting stick. Dudley and Harry were thrown out of the kitchen, but overheard the conversation through the door: Harry forced to listen under the crack, while Dudley looked through the better position: the peephole in the doorknob.
When Vernon and Petunia gave Dudley's second bedroom to Harry, Dudley threw a temper tantrum, claiming that he needed the room. In an attempt to change his parents' minds: Dudley screamed, hit his father with his Smelting stick, threw up on purpose, kicked his mother, and threw his pet tortoise through the greenhouse roof. When the mail arrived, Dudley was sent to collect it (in an attempt by Vernon to be "nice" to Harry). From the hall, Dudley yelled that Harry had received another letter. Vernon wrestled Dudley to the ground and took the letter away, which was made difficult by Harry clinging on to Vernon's neck.
Within a week, 24 or more letters arrived for Harry; Dudley wondered who on Earth would want to talk to Harry so badly. When so many letters for Harry arrived, Vernon, having had enough, told the family to get ready to leave. Dudley angered his father when he dawdled, trying to pack his television, VCR and computer into his bag. By nightfall, Dudley was in an unpleasant mood; he was hungry, had missed five TV shows he wanted to watch and had not gone so long without shooting an alien on his computer. At the Railview Hotel, Dudley shared a room with Harry; while Harry remained awake, Dudley fell asleep almost immediately.
In the Hut on the Rock
The following day, Vernon brought Dudley and the family to the Hut on the Rock well out in the sea. Using some mouldy blankets, Petunia made Dudley a bed on the couch, which he was very unhappy with, while she and Vernon took the second bedroom and Harry was left on his own to find comfort. At midnight, when Harry's birthday came, Dudley was jerked out of his sleep by a loud crashing outside the hut, and asked sleepily where the cannon was; a few moments later, the hut's door was knocked off by Rubeus Hagrid. Dudley remained on the couch, frozen in fear. When Hagrid nudged him out of the way, Dudley ran and hid behind his mother.
When Vernon insulted Albus Dumbledore and after Hagrid informed him that Harry was going to Hogwarts School of Witchcraft and Wizardry, Hagrid used magic to sprout a pig's tail from Dudley's bottom (because Dudley was helping himself to Harry's birthday cake), which caused immense pain — something that Harry found enjoyment in.
Arrival at school
After dropping Harry off at King's Cross Station on 1 September, the Dursleys took Dudley to a private hospital in London to have the tail removed before he went to Smeltings. Over the course of the school year, he grew even more massive: so much so that his bottom drooped over each side of his chair.
Tormenting his cousin
- "Today's your birthday. How come you haven't got any cards? Haven't you even got any friends at that freak place?"
- —Dudley taunting Harry on 31 July[src]
In June, Dudley accompanied his parents to King's Cross Station to pick Harry up for the summer holidays. In spite of his morbid weight, his clothes were curiously depicted as loose, as he had to hitch up his trousers "which were slipping down his fat bottom" during a conversation with Harry. One morning during breakfast, Dudley wanted more bacon. He asked Harry to pass the frying pan: when Harry said he forgot the magic word (meaning "please"), Dudley fell out of his chair with a crash that shook the whole kitchen. Obviously, Dudley had been trained by his parents by that time to hate and fear anything that had anything at all to do with Harry and his world.
On 31 July, Dudley taunted Harry about not receiving any birthday presents from his friends. When Harry pretended that he was going to set a bush on fire by saying pretend magic words, Dudley ran to his mother, frightened. That night, the Dursleys (sans Harry) hosted a dinner party for clients of Vernon's — the Masons. At eight o'clock, Dudley was by the front door, waiting for Mr and Mrs Mason to arrive. He offered to take their coats and offered his arm to accompany Mrs Mason to the dining room a while later.
Learning about Sirius Black
By summer, Dudley was even fatter. At some point, he complained about the walk between the living room and the kitchen, so his father installed a new TV in the kitchen as a welcome-home-for-the-summer present. Dudley sat at the TV all day, eating constantly. He gained five chins.
Along with his parents and Harry, Dudley learned one day of an escaped convict named "Sirius Black," whom the newscasters warned was armed and dangerous. Vernon was constantly complaining about lack of security and punishment, stating that hanging was the only way to handle people like Black.
On 31 July, Dudley's Aunt Marge came to visit their house. When Marge arrived, Dudley waddled into the hall to greet her. Marge seized him in a one-armed hug and kissed him on the cheek. Harry, sure that Dudley only put up with this treatment because he was well paid for it, noticed a twenty-pound note clenched in his fat hand behind his back. When Marge was blown up by Harry because of her voracious veracity, Dudley showed almost no emotion and continued watching TV. It can be assumed that he was used to the odd things that happened whenever his cousin was around.
By the summer of 1994, Dudley had grown so large that the school outfitters at Smeltings Academy did not stock knickerbockers big enough for him anymore; he had reached roughly the size and weight of a baby killer whale. To rectify the situation, the school nurse forced a diet regime upon Dudley, which emptied his eating habits of all the things he enjoyed: fizzy drinks, cakes, chocolate bars, burgers, doughnuts, chips, etc. and replaced them with fruits and vegetables — things that Vernon called "rabbit food." Dudley was not pleased and threw numerous tantrums about it. To make Dudley feel better, Petunia insisted that the whole family follow the diet, as well: to raise Dudley's morale, she also tended to give him more to eat than Harry (who, unbeknownst to Dudley, kept a secret stash of food in his bedroom). When Vernon left the kitchen to collect the post, Dudley stole his grapefruit quarter.
The next day when the Weasleys arrived to take Harry to the Quidditch World Cup, Dudley nervously ran his hands over his backside: remembering the incident with Hagrid in 1991, he was unwilling to present the same target to wizards again.
As the Weasleys returned to the Burrow through the Floo Network, Fred "accidentally" dropped numerous sweets in brightly coloured wrappers on the floor, knowing Dudley would eat one of them. The sweet revealed to be a Ton-Tongue Toffee, caused Dudley's tongue to expand greatly and cause him pain. Before allowing Mr Weasley to fix it, Petunia tried to rip the tongue out of Dudley's mouth, which nearly suffocated him. His tongue was more than four feet long before the Dursleys allowed Mr Weasley to shrink it.
In 1995, Dudley took up boxing, which gave him even more prominence over other children. As a result, he lost weight and became less spoiled. However, he was still described as "vast as ever," but it was implied that his bulk was more muscle than fat because of the boxing. He would roam the streets with his gang, vandalising public property, taking up smoking and terrorising younger children. After taking up his workout regime, Dudley became boxing champion at his school. At one point they beat up a boy for "cheeking him".
Along with his parents, Dudley learned that Lord Voldemort had returned to a physical body, with the intent of subjugating both the wizarding and Muggle communities once again. On his way home one night with his gang, Dudley ran into Harry. He and Harry were attacked in the street by two dementors, sent by Dolores Umbridge to harm Harry (unknown to Harry). Harry's stag Patronus saved them from being kissed, but Dudley, confused by what had happened, pinned the blame for the attack on his cousin, as he could not see the Dementors. The encounter with the Dementors forced Dudley, for the first time, to recognise the kind of person he really was: a cruel bully. It was a terribly painful moment for him, and led to him changing his ways.
Visited by Albus Dumbledore
- "The best that can be said is that he has at least escaped the appalling damage you have inflicted upon the unfortunate boy sitting between you."
- —Albus Dumbledore's damning assessment of Vernon and Petunia's spoiling of Dudley[src]
When Albus Dumbledore paid a personal visit to the Dursleys in 1996, he showed pity for Dudley, blaming the Dursleys for the "appalling damage" their parenting inflicted on their son. Dudley was very confused by this statement, and did not show any signs of planning to rectify his parents' "mistakes." As Harry and Dumbledore leave, Dumbledore told the Dursleys that in summer 1997 that they have to evacuate their house to protect themselves from becoming the victims of Lord Voldemort and Death Eaters.
Hiding from Death Eaters
After Harry arrived at Number Four, in 1997, Dudley made at least one known attempt to reconcile with Harry. Dudley placed a cup of tea outside Harry's room. However, Harry initially misinterpreted the gesture as another prank, as Dudley had placed the cup on the floor and Harry stepped on it by accident. When Harry parted ways with the Dursleys, Dudley was the only member to bid Harry farewell.
When Dudley was attacked by the Dementors he saw himself, for the first time, as he really was. This was an extremely painful but ultimately salutary lesson and began the transformation in him. He shook Harry's hand and thanked him for saving his life. The members of the Order of the Phoenix escorting the Dursleys into hiding were not satisfied by this and thought a more adequate apology was in order, but the Dursleys left with nothing more to say, Harry himself noting that Dudley's awkward thanks was the Dursley equivalent of a heartfelt expression of gratitude.
In Dudley's adult life, he got married and became a father of two. He and Harry remained on "Christmas card terms," and Harry sometimes took his children to Dudley's when they were in the neighbourhood, occasions dreaded by James, Albus, and Lily. During these visits Dudley and Harry would sit silently together rarely talking while their children interacted and played together. It is unknown if Dudley ever returned to Little Whinging or if their family had stayed in the place they were relocated to, or if they had moved elsewhere. By 2020, Dudley's mother had passed away.
- "Aunt Petunia often said that Dudley looked like a baby angel — Harry often said that Dudley looked like a pig in a wig."
- —Dudley's appearance in his early years[src]
Dudley has watery blue eyes and thick blond hair. Growing up, Dudley was extremely fat, at least four times Harry's size. Harry often thought Dudley looked like a pig in a wig. In 1994, he had "reached the size and weight of a young killer whale" — somewhere between 265 and 353 pounds. Dudley was too large to fit in a school uniform, so was forced to go on a diet by his school, which was largely comprised of food which Vernon called "rabbit food" (fruits and vegetables) which Dudley rarely ate otherwise. Vernon and Petunia usually made excuses on why he was large, such as that his poundage was really "puppy fat" or that he was a "growing boy." Dudley mostly ate junk food, hated exercise, and often played video games. When Harry and the Dursleys ate breakfast Dudley's flab would often hang off the chair because he was too big and eventually a TV was bought for the kitchen after Dudley had complained about the distance from the living room to the fridge. He was also incredibly lazy. This may have had something to do with his weight problem.
However, by 1995 after he was attacked by Umbridge's dementors, Dudley had taken up boxing and weight lifting, and lost a great deal of weight. Before to the Dursleys left Privet Drive, he appeared "large, blond, and muscular," wearing a leather jacket.
Personality and traits
Dudley was an unpleasant and spoiled child. His parents spoiled him to the point of becoming grossly obese, demanding, selfish, and manipulative, but most of all, extremely ungrateful. During his eleventh birthday, he screamed when he received one gift fewer than the previous year, making his parents promise to buy him two more, and pretended to cry when he realised Harry would have to come with him for his birthday trip to the zoo.
Dudley had an awful habit of bullying children who were weaker and as much as five years younger than he was, and when he forgot his fear of Harry's powers, callously insulted him in any way possible, even jeering at Harry about his obviously disturbing nightmares.
Despite being fairly manipulative, Dudley appeared to have a low level of intelligence. In 1991, whilst Rubeus Hagrid was attempting to enter the Hut-on-the-Rock, he foolishly quoted "Where's the cannon?" showing poor common sense. In the school holiday of 1994, he received a dismal school report from Smeltings Academy, which included very poor academic results as well as reports of bullying others.
However, in 1995, Dudley faced dementors for the first time. Though a Dementor attack typically forced a person to re-live the worst moments of their life, Dudley's life-so-far of luxury and greed contained no "worst moments," and therefore, during the attack, Dudley saw himself the way he truly was: a spoiled, rotten and cruel bully. He was thus forced, rather harshly, to realise he needed to change his ways. This led to him regretting his treatment of Harry and his later attempts at reconciliation. The cousins would have a relatively good relationship by 2017: Dudley and Harry visited each other, while their children played together.
- "Little tyke wants his money's worth, just like his father."
- —Vernon Dursley regarding Dudley's tantrum[src]
Vernon and Petunia Dursley spoiled and coddled their son as much as they neglected and abused their nephew Harry. They appeared to buy Dudley anything he wanted, often apparently to waylay a tantrum (Vernon going so far as bribing him to accept a kiss from Aunt Marge). They indulged their son with treats and activities both out of blind adoration for the boy and as a means of emphasising to Harry what he was missing. They were generally in denial of the obesity brought on by Dudley's gluttony, which they wrote off as being either the healthy appetite of a growing boy or that his poundage was really "puppy fat" and were completely oblivious to the fact that Dudley did not have friends, so much as a schoolyard gang and victims.
While Vernon consistently praised his son as if he was extremely masculine and robust, Petunia infantilised Dudley, calling him "Diddykins" well in to his teen years, appearing heartbroken to have to put Dudley on a much-needed diet and even bursting into tears when Dudley showed marginal affection for Harry.
- Dudley: "I don’t think you’re a waste of space."
- Harry Potter: "Well… er… thanks, Dudley."
- Dudley: "You saved my life."
- — Harry’s farewell to the Dursleys and Dudley's gratitude[src]
Dudley and his cousin Harry did not get along very well for most of their early lives. Like his parents, Dudley only thought of Harry as a huge burden to the family. While Vernon and Petunia treated Harry poorly, they spoiled Dudley to the extreme. Dudley constantly bullied Harry throughout their childhood, but did his best not to provoke him after he found out that Harry was a wizard, though the two still often argued and traded insults. This changed after Harry saved Dudley from a pair of dementors that attacked them during the summer of 1995. When the Order of the Phoenix placed the Dursleys into hiding to keep them safe during the height of the Second Wizarding War, Dudley was the only member of the family to express concern for Harry's safety, asking his parents why Harry was not accompanying them and where he would go, if not with them. He also expressed remorse for his earlier treatment of Harry and the two shook hands before the Dursleys left.
After the Second Wizarding War, Dudley later became a cousin-in-law to Harry's wife Ginevra Weasley and a first cousin once removed to Harry and Ginny's children, James, Albus, and Lily Potter. Dudley and Harry eventually reconciled as adults, remaining on "Christmas card terms" and visiting each other occasionally. At these times, Harry's three children and Dudley's children would all play together while their fathers would sit together quietly.
When his mother, Petunia, died, Dudley was still on good terms with Harry. While cleaning out her possessions, he found the blanket that Harry had been wrapped in when he arrived at 4 Privet Drive and mailed it to him, believing that Petunia wanted him to have it.
Dudley means "from the meadow." It is also a large town located in the West Midlands county of England which, as with the town of Dursley, is known for its coal mining in the Victorian era. J. K. Rowling implied that she took the name from the town, commenting "maps are a great source for names", then adding "Dursley and Dudley and Snape are all places I can’t visit anymore."
Dursley is a town in Gloucestershire, England. Rowling has commented that she visited the place as a child and hated it, which likely affected her choice of surname for the awful family, remarking "I don't imagine I'm very popular in Dursley." Rowling chose the name because it sounded "dull and forbidding".
Behind the scenes
- Dudley was portrayed by Harry Melling in the film series.
- It is never made clear if Dudley was aware of Harry being a wizard before the latter read his Hogwarts letter. However, since he was said to avoid being in the same room with Harry after the truth was said, it can be assumed that Vernon and Petunia never told him. In addition, his parents probably did not want him to believe in magic.
- In one of Harry's several letters to Sirius Black in the summer of 1994, he says that Dudley threw his PlayStation out of a window after he was caught sneaking doughnuts into his room. However, this is an anachronism, as the Sony PlayStation was not released anywhere until December 1994 (in Japan) and in Britain until September 1995. However, customers with influence could obtain a "test set" for a high cost.
- Coincidentally, the real name of the actor who plays Dudley is Harry.
- Although not mentioned in the books, J. K. Rowling said during the Dementor attack, Dudley saw himself the way he truly was: spoiled rotten and a cruel bully, making him realise, rather harshly, that he needed to change. This led to him regretting his treatment of Harry and his attempt later at reconciliation.
- In the books, Dudley's hair is blond, but in the films it is dark brown.
- Dudley is portrayed as fat in the books and films. In an interview on the Harry Potter and the Prisoner of Azkaban film DVD, Harry Melling stated he had lost weight and had to wear a fat suit in order to show Dudley's chubbiness.
- J.K. Rowling has stated that she originally planned to have Dudley have a wizard child in the Epilogue but decided that no magical blood would ever get past Uncle Vernon's DNA.
- Dudley did not appear in either the film adaptation of Harry Potter and the Goblet of Fire nor the film adaptation of Harry Potter and the Half-Blood Prince, as the film script writers removed the Privet Drive matter to fit each book into one film.
- Dudley and his gang once beat up a boy named Mark Evans. Though Dudley's maternal family are the Evans, Mark is not closely related to the Evans family, nor to Dudley: whether there is a distant link is unknown.
- The scene where Dudley reconciles with Harry does not make it into the film, though it was filmed and is included as a deleted scene in the DVD of Harry Potter and the Deathly Hallows: Part 1.
- In the film adaptation of Harry Potter and the Philosopher's Stone, Rubeus Hagrid mistakes Dudley for Harry when he comes to get Harry at the Hut-on-the-Rock and comments on his weight.
- In Harry Potter and the Philosopher's Stone, when the Dursley family visit the zoo with Harry on Dudley's eleventh birthday they are accompanied by Dudley's best friend, Piers Polkiss. But in the film adaptation Piers Polkiss does not appear.
- Apart from the movies, Melling also voiced Dudley in the Order of the Phoenix video game.
- Dudley is similar to Draco Malfoy in some ways. Both are boys who are the only children of their parents. Both are spoiled, although Draco's father was firm at times and had high expectations for him. Draco has white-blonde hair and Dudley is blonde in the books. Both have mothers who are named after flowers (Petunia Dursley and Narcissa Malfoy). Both boys' parents enjoyed the idea of a prominent, wealthy social status - the Malfoys are a very wealthy Wizarding family, while the Dursleys have a goal of moving up in society. Harry was bullied by both Draco and Dudley for years - Dudley in the Muggle world, Draco in the wizarding world - though he eventually reconciles with both of them.
