Harry Potter Characters
Jackie and I have loved Harry Potter for years. We have read and listened to every book more than once and watched every movie. I thought it would be the perfect time to give a little refresher on the Harry Potter characters.

Jim Dale, the award-winning audiobook narrator, used 146 unique voices for characters in The Deathly Hallows. It set a new record in the Guinness Book of World Records. This list will not include all the characters in the Harry Potter world, because that would be too much. But with the new HBO series set to release at Christmas 2026, I wanted to give a list of the main characters and the important secondary characters. Don’t worry, any spoilers will be hidden in a drop-down.
Harry Potter changed children’s literature. If my research is correct, Harry Potter and the Goblet of Fire was the first book to have a midnight launch party in July of 2000. Harry Potter also normalized adults reading kids’ books! There is a reason that Harry Potter Special Edition Books exist, and it is not because younger kids want them!
If you want a reminder about the Harry Potter Books in Order, that may help your memory of the characters as well.

The summer that Harry turns 11, he receives his invitation to attend Hogwarts School of Witchcraft and Wizardry. He is sorted into Gryffindor after he asks the Sorting Hat not to put him in Slytherin.
