A Man Called Horse is a 1970 Western film directed by Elliot Silverstein, produced by Sandy Howard, and written by Jack DeWitt. It is based on a short story of the same name by the Western writer Dorothy M. Johnson, first published in 1950 in Collier's magazine and again in 1968 in Johnson's book Indian Country. The basic story was used in a 1958 episode of the television series Wagon Train, also titled "A Man Called Horse". The film stars Richard Harris as the titular character, alongside Judith Anderson, Jean Gascon, Manu Tupou, Corinna Tsopei, Dub Taylor, and James Gammon.

Partially spoken in Sioux, the film tells the story of an English aristocrat who is captured by the Sioux people. The film was a Mexican-American co-production filmed on location in Arizona and the Mexican states of Durango and Sonora. It received generally positive critical reviews, and was a financial success, spawning two sequels; The Return of a Man Called Horse (1976) and Triumphs of a Man Called Horse (1983).
