10 Oldest Characters In The Harry Potter Universe

Age: 665+ (now deceased)

In Harry Potter and The Philosopher's Stone, we learn that alchemist Nicolas Flamel celebrated his 665th birthday at some point before the events of the novel, which takes place in the 1991 - 1992 school year.

This means that Flamel is likely a bit older than this, since the tidbit about his birthday is extracted from an "old" book, read by Hermione.

Unlike Armando Dippet - who did not extend his life via any magical means - Flamel, along with his older wife, Perenelle, utilised the power of the philosopher's stone to make themselves immortal. However, after Voldemort (acting through Professor Quirrell) nearly acquired the stone, Flamel and Dumbledore both agreed that it should be destroyed, which meant that the alchemist and his wife could no longer sustain their existence.

And so, the Flamels died painlessly and peacefully. Nicolas will actually appear in the Fantastic Beasts sequel later this year, where we'll possibly learn more about his past relationship with Dumbledore.
