Fat Lady Portrait

Large portrait of the Fat Lady in a pink dress guarding the entrance to Gryffindor Tower.

The Fat Lady Portrait, a plump witch in a pink dress, serves as the steadfast guardian of Gryffindor Tower's entrance throughout the Harry Potter series, her painted vigilance ensuring only those with the correct password gain access to the common room. Introduced prominently in Harry Potter and the Prisoner of Azkaban, she becomes a recurring fixture symbolizing the house's security and whimsy. Though her role remains consistent, she faces dramatic moments of peril, fleeing her frame during a violent attack, only to return with enhanced protections in subsequent books.
