Immortality is the magical ability to live forever. Immortality is one of the known limits to magic; it is nearly impossible to make oneself immortal; the only known and working ways are making and using a mystical object of great power to sustain life (such as the Philosopher's Stone created by Nicolas Flamel or a Horcrux, the latter having been used by Lord Voldemort).
If one were to possess the three Deathly Hallows, it is fabled that they would possess the tools to become the "Master of Death". However, being a true "Master of Death" is to be willing to accept that death is inevitable.
Immortality is not to be confused with amortality, which is for something being unable to die due to never having been alive.
Elixir of Life
The Philosopher's Stone, a stone created by famous alchemist Nicolas Flamel, is able to produce the Elixir of Life, one of the known means of immortality. In 1991 and 1992, a weakened Lord Voldemort tried to gain possession of the Stone so he could rise again after his downfall ten years prior. The Stone was then destroyed by Albus Dumbledore and Nicolas Flamel himself in order to prevent this from happening again. With the destruction of the Philosopher's Stone, all individuals who were immortal because they drank the Elixir of Life (like Flamel and his wife) died after the supply of Elixir ran out.
The Elixir does not truly grant immortality, as it only extends the drinker's lifespan, as opposed to rendering them invulnerable to damage. Thus, it is possible for them to die even while drinking the potion. It must be drunk regularly, for all eternity, to continuously live on. Furthermore, the potion does not rejuvenate youth, as if one lives past their natural lifespan, they would continue to age, eventually taking on a decrepit and ancient appearance, as Nicolas did.
Lord Voldemort, who was so fearful of death, intended to split his soul into seven pieces, six pieces residing in Horcruxes and the seventh piece in his body. He is the only wizard in history to have created more than one Horcrux and therefore considered the one closest to true immortality. Unbeknownst to him, his soul was split a seventh time; after his killing curse rebounded after trying to murder an infant Harry Potter, a shard of his soul attached itself to the baby. The seven Horcruxes were all items owned by reputable people that played an important — or scarring — role in his life, including the Four Founders. His best plans were, however, beaten due to his arrogance, when Regulus Black, Albus Dumbledore, Harry Potter, Ron Weasley and Hermione Granger discovered his secret and found each one of his Horcruxes and destroyed them (Vincent Crabbe also destroyed one, but he did it unknowingly and likely did not know that Voldemort had any at all), returning Voldemort his mortality and led to his eventual and final death.
Whenever phoenixes die, whether from old age or something like a Killing Curse, they will always be reborn from their remaining ashes, technically making them immortal. They are so far the only living beings who possess natural immortality, as it seems there is no known method to truly and permanently kill a phoenix. They are also the only creatures who defy the absolute law that nothing can truly bring back the dead. A phoenix bursting into flames to die and then to be reborn (usually by old age) is known as a Burning Day.
Fawkes, the pet phoenix of Albus Dumbledore, has been reborn from old age many times, and revived instantly from his remaining ashes when swallowing Lord Voldemort's Killing Curse meant for Dumbledore during their duel in the Ministry Atrium, he exploded after swallowing it.
Unicorn's bloodUnicorn blood has the gift to save a drinker from death even when they are nearing it. This makes it similar to the Elixir of Life, which also extends the life of the drinker. However, if taken, it will lead the drinkers to be cursed for all life, as they had slayed an innocent creature for self-preservation. Such an act was considered to be only for those who had nothing to lose, and everything to gain would commit. It has never been clarified if a second person who never killed a unicorn drank its blood would be cursed the same.
Quirinus Quirrell drank unicorn's blood while he was possessed by Voldemort, in order to maintain his waning life due to the strain of sharing body with the Dark Lord, until they can gain access to the Elixir of Life. Two years later, Voldemort had Peter Pettigrew to craft a Dark potion that requires unicorn blood as one of the ingredients to regain his rudimentary physical form, which would require him continuous intake of the potion to maintain the little health he regained.

Behind the scenes
- Many wizards believe that the person who masters the three Deathly Hallows (which are the Elder Wand, the Resurrection Stone and the Cloak of Invisibility) will be the Master of Death and will achieve some form of immortality, while a larger proportion dismiss both the concept and the three artefacts as a fairy-tale. However, becoming immortal from gathering the three is a misconception, as being a true Master of Death is realising and accepting the fact that everyone will die and there are worse things than death. Harry Potter collected the three Hallows and was willing to accept death and so became the Master of Death. According to Dumbledore, the Hallows were a desperate man's dream, dangerous, and a lure for fools. Indeed, many died in their pursuit of the Hallows and the "Master of Death" legend.
- Voldemort chose the usage of Horcruxes for his immortality due to his refusal to be reliant on anything but himself; he found the usage of the Elixir of Life to be dependent on him drinking it for all eternity and the stone required to create the potion, which he could not accept. Relying on external vessels for his soul fragments, however, was acceptable, since they are magical extensions of himself.
