"Knocks objects and creatures backwards."
— Description[src]

The Knockback Jinx[1] (Flipendo)[1] was a jinx that knocked the target backwards.[2] While prominently used for duelling, it could also be used to push heavy objects.[3] It was covered in Quentin Trimble's The Dark Forces: A Guide to Self-Protection, a Defence Against the Dark Arts textbook.[1]


"Today we will be learning the Knockback Jinx–an excellent spell for pushing things out of the way!"
— Professor Flitwick introducing this spell to first-year students in Charms class[src]

The Knockback Jinx in action

During the 1984–1985 school year at Hogwarts School of Witchcraft and Wizardry, Professor Filius Flitwick taught his first-years how to cast this jinx in Charms class.[2]

During the 1991–1992 school year, this jinx was instead taught to first-years in the Defence Against the Dark Arts class by Professor Quirinus Quirrell, who were taught how to cast the spell both defensively and practically.[8]

A spellbook detailing how to cast this spell could be found in Ollivanders.[8]

This spell was heavily used by volunteer members of the Statute of Secrecy Task Force to help knock back beasts that were guarding various Confoundables, such as gnomes, pixies and trolls, to overpower the strange artefacts and return them to their rightful place.[4]


The Knockback Jinx, depending on the point of impact, might feel like a blow to the chest, knocking back a victim or object,[1] or might feel like being knocked over the head with a frying pan, leaving the victim a bit disoriented. A "loud bang" was also emitted when cast.[9] The jinx could also break fragile objects.[8][3]

Knockback Jinx Duo,[8] Flipendo Tria[8] and Flipendo Maxima[10] were all more powerful variations of the Knockback Jinx which all knocked the target back with greater force.

Known uses

"There was a loud bang and he felt himself flying backwards as if punched; as he slammed into the kitchen wall and slid to the floor, he glimpsed the tail of Lupin's cloak disappearing round the door."
— Remus Lupin uses this spell on Harry Potter[src]
Caster(s) Date Notes
Merula Snyde 1984–1985 school year Used this jinx on Jacob's sibling in the Clock Tower Courtyard before the start of their duel.[7]
Jacob's sibling 1986–1987 school year Attempted to use this jinx on Corrine Cribb with wandless magic in Knockturn Alley, although Cribb was able to dodge the jinx.[11]
1988–1989 school year Frequently used this jinx in Defence Against the Dark Arts class to repel Pixies.[12]
Used this jinx on Chiara Lobosca to knock her out of the way of Ismelda and her friends' Full Body-Bind Curse.[13]

Ismelda Murk 1988–1989 school year Used this jinx to knock Jae Kim off this broomstick during the final round of the Tournament of Clubs, rendering him unconscious.[17]
Dobby (possibly) 30 May, 1993 After Lucius Malfoy realised that Harry Potter had freed Lucius's House-elf, Dobby, with a sock, he made to attack Harry. To protect Harry, Dobby used magic that sent Lucius flying backwards. As this was accomplished by House-elf magic - without a wand - it was probably not the same as a traditional Knockback Jinx, but the effect was certainly comparable.[18]

Draco Malfoy September, 2020 Used in a duel against Harry Potter in Harry's house.[21]

Known practitioners


The spell is derived from the English words "flip" and "end", simply meaning "to flip someone onto their end".
