10 Oldest Characters In The Harry Potter Universe
7. Elphias Doge
Age: 137+
Member of the Order Of The Phoenix and a key player in the first and second wizarding wars, Elphias Doge was a good friend of Albus Dumbledore, and even started Hogwarts on the same day as him.
Known for wearing silly and eccentric hats, Doge actually wrote Dumbledore's obituary for The Daily Prophet, something that prompted Harry to go and talk to him during Bill and Fleur's wedding. This wedding is the last we see or hear of him, so it's entirely possible that he could still be alive today.
If he started Hogwarts on the same day as Dumbledore, that places his birthday around the same year as his old friend's - 1881 - making him at least 137 today.
