Which Hogwarts house is associated with the character Harry Potter?

Harry Potter is associated with Gryffindor at Hogwarts.

The Sorting Hat places Harry in Gryffindor when he begins his first year at Hogwarts. Ron Weasley and Hermione Granger are also members of the house, making it the main student community for the series' central trio. Gryffindor's common room is located in a tower at Hogwarts.

The house is named after Godric Gryffindor, one of Hogwarts' four founders. It is traditionally linked with bravery, nerve and chivalry, though the novels show that its students have varied personalities and weaknesses.

Harry could have been placed in Slytherin, but his preference helps influence the Sorting Hat's decision. That scene is why readers sometimes describe house placement as a simple personality test; in the story, the Hat considers qualities, potential and choice rather than using only one fixed trait.
