Katie Bell (born 1978) is a chaser on the Gryffindor Quidditch team. She joined the team in her second year at Hogwarts, the same year Harry joined. Katie, who has dirty-blond hair and brown eyes, is friends with fellow chasers Angelina Johnson and Alicia Spinnet.
She was mentioned during a Quidditch match against Slytherin in book three when Montague “accidentally” grabbed her head instead of the quaffle. In book five she joined Dumbledore’s Army, an organization formed by Harry to teach fellow students practical Defense Against the Dark Arts. Also that year, Ron, the new keeper for the Gryffindor team, hit her in the face with a quaffle during Quidditch practice, giving her a nosebleed. In a failed attempt to help her, Fred Weasley gave her the wrong end of a Nosebleed Nougat, a candy in which one half causes a nosebleed and the other half cures it. As a result: the nosebleed worsened, rather than stopping, and eventually practice had to called off because she was losing too much blood.
In book six, Katie is the only remaining member of the Quidditch team from Harry’s first year. She encourages Harry, the new team captain, to hold tryouts for everyone, even returning players. Katie plays a major role in Draco Malfoy’s scheme to kill Dumbledore. Madam Rosmerta, under an Imperius Curse from Draco, gives Katie a cursed necklace to deliver to Dumbledore. Katie foils the murder attempt by accidentally touching the necklace herself when the package rips open during an argument with her friend Leanne. Because of a small hole in her glove, only a tiny part of her skin came in contact with the necklace, yet she was still injured enough to warrant a long visit to St. Mungo’s, the wizard hospital. She was released in time to play in the final Quidditch match against Ravenclaw, and helped Gryffindor go on to win the Quidditch Cup.
