Lego Harry Potter is a Lego theme based on the films of the Harry Potter series. Models of important scenes, vehicles and characters were made for the first five films released. The first sets appeared in 2001, to coincide with the release of the first film Harry Potter and the Philosopher Stone (Harry Potter and the Sorcerer's Stone in the United States). Subsequent sets were released alongside the new films, up until Harry Potter and the Order of the Phoenix.
