Which J.K. Rowling book introduced the magical sport of Quidditch?

Harry Potter and the Philosopher’s Stone introduced the magical sport of Quidditch.

Harry first learns about Quidditch during his early days at Hogwarts. The sport is played on broomsticks, with two teams of seven players competing to score through three hoops while also attempting to catch the Golden Snitch. Harry becomes Gryffindor’s Seeker, the player assigned to pursue the Snitch.

The novel establishes the basic rules, positions, and rivalries that make Quidditch an important part of school life. Gryffindor matches against Slytherin provide recurring moments of competition, while Harry’s talent helps connect him with his housemates and the wider history of the school.

Quidditch is fictional, but Rowling’s creation later inspired real-world adaptations played on foot. Those versions usually use simplified rules and equipment, so they should not be confused with the broomstick sport as described in the novels. The original fictional game remains one of the best-known elements of the series.
