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 (six of which were produced by Universal) 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 1843 short story.

The film was among the earlier movies with an almost continuous music score, and it helped to create and popularize the psychological horror subgenre by emphasizing atmosphere, eerie sounds, the darker side of the human psyche, and emotions like fear and guilt to deliver its scares.
