Viva Zapata! is a 1952 American Western film directed by Elia Kazan and starring Marlon Brando. The screenplay was written by John Steinbeck, using Edgcomb Pinchon's 1941 book Zapata the Unconquerable as a guide. The cast includes Jean Peters, and in an Academy Award-winning performance, Anthony Quinn.

The film is a fictionalized account of the life of Mexican revolutionary Emiliano Zapata from his peasant upbringing through his rise to power in the early 1900s and his death in 1919.

To make the film as authentic as possible, Kazan and producer Darryl F. Zanuck studied the numerous photographs that were taken during the revolutionary years, the period between 1909 and 1919, when Zapata led the fight to restore land taken from common people during the dictatorship of Porfirio Díaz.

Kazan was especially impressed with the Agustín Casasola collection of photographs, and he attempted to duplicate their visual style in the film. Kazan also acknowledged the influence of Roberto Rossellini's Paisan (1946).
