Quidditch () is a fictional sport invented by author J. K. Rowling for her fantasy book series Harry Potter. It first appeared in the novel Harry Potter and the Philosopher's Stone (1997). In the series, Quidditch is portrayed as a dangerous but popular sport played by witches and wizards riding flying broomsticks. Matches are played on a large oval pitch with three ring-shaped goals of different heights on each side, between two opposing teams of seven players each: three Chasers, two Beaters, the Keeper, and the Seeker.
