Pottermore was the original name of J.K. Rowling’s official Harry Potter fan website, launched in 2011.
The site combined interactive features with new writing by Rowling, including background details about characters, places, and wizarding traditions. Users could be sorted into Hogwarts houses, receive wand assignments, and explore illustrated moments from the books.
Pottermore was later redesigned and renamed WizardingWorld.com in 2019. The name change is why both Pottermore and Wizarding World appear in discussions of Rowling’s official digital platform, but Pottermore is the launch-era title.
