The World, the Flesh and the Devil is a 1959 American science fiction doomsday film written and directed by Ranald MacDougall. The film stars Harry Belafonte, who was then at the peak of his film career. The film is set in a post-apocalyptic world with very few human survivors. It is based on two sources: the 1901 novel The Purple Cloud by M. P. Shiel and the story "End of the World" by Ferdinand Reyher.

Harry Belafonte was an American singer, actor, and civil rights activist who popularized calypso music with international audiences in the 1950s and 1960s. Belafonte's career breakthrough album Calypso (1956) was the first million-selling LP by a single artist.
