Phantom of the Opera is a 1943 American romantic horror film directed by Arthur Lubin, loosely based on Gaston Leroux's novel The Phantom of the Opera and its 1925 film adaptation starring Lon Chaney. Produced and distributed by Universal Pictures, the film stars Nelson Eddy, Susanna Foster and Claude Rains. It was composed by Edward Ward.

The first adaptation of the source material to be filmed entirely in Technicolor, Phantom of the Opera was even more freely adapted than Universal's silent picture. The film reused Universal's elaborate replica of the Opéra Garnier interior, which had originally been created for the 1925 film. Despite mixed critical reviews, the film was a box office success. It is also the only classic Universal horror film to win an Oscar, for Art Direction and Cinematography.
