The Black Cat is a 1934 American pre-Code horror film directed by Edgar G. Ulmer and starring Boris Karloff and Béla Lugosi. It was Universal Pictures' biggest box office hit of the year, and was the first of eight films to feature both Karloff and Lugosi. In 1941, Lugosi appeared in a comedy horror mystery film with the same title, which was also named after and ostensibly "suggested by" Edgar Allan Poe's short story.

Edgar Georg Ulmer was a Jewish-Moravian, Austrian-American film director who mainly worked on Hollywood B movies and other low-budget productions, eventually earning the epithet 'The King of PRC', due to his extremely prolific output for the Poverty Row studio. His stylish and eccentric works came to be appreciated by auteur theory-espousing film critics in the years following his retirement. Ulmer's most famous productions include the horror film The Black Cat (1934) and the film noir Detour (1945).
