The Harry Potter Trading Card Game Quidditch Cup Expansion (or simply Quidditch Cup, for short) was the second set of cards of Harry Potter Trading Card Game, and the first expansion to the base set.
It was introduced in November 2001, and, like the base set, its 80 cards were based on scenes from Harry Potter and the Philosopher's Stone book by J. K. Rowling. This expansion introduced the Quidditch lesson type and Match cards.
