Which Hogwarts House did Cedric Diggory belong to?
Answer Hufflepuff
During Harry's time at Hogwarts, students in Hufflepuff House were unfairly viewed as — how to put this lightly — dorks. Cedric Diggory upended this stereotype. He was a prefect, captain of the Hufflepuff Quidditch team, a Triwizard Cup champion, and an outstanding student. Being tall and handsome didn't hurt, either. He met his end when Voldemort directed Wormtail to murder him during the Triwizard Tournament.
