160 Hard Harry Potter Trivia Questions and Answers
July 9, 2025
Whether you’ve been waiting for your Hogwarts letter since 1997 or recently became a Potterhead, the Harry Potter series has been beloved by children and adults alike for nearly three decades. Written by J.K. Rowling, the seven books have also inspired an eight-movie franchise, a Broadway play, a theme park, an upcoming HBO Max series, countless criminally expensive LEGO sets, and even hundreds of competitive Quidditch teams (recently rebranded as “Quadball”). While the Harry Potter universe has been under fire in recent years due to the author’s views on transgender rights—which raises the age-old question of whether we should boycott, or even ban, media created by authors who hold views with which we disagree—its influence on the past and current cultural and literary landscape is undeniable. Care to test your knowledge of the Wizarding World? Read on for Harry Potter trivia questions, organized by book.
