I Killed Geronimo is a 1950 American Western film about the Chiricahua Apache leader Geronimo. Directed by John Hoffman and starring James Ellison, Virginia Herrick, and Chief Thundercloud in the role of Geronimo, the film has been described as a "silly but likeable" B movie. It is based around the fictional murder of Geronimo - who in reality died of pneumonia at the age of 80 after a fall from his horse in February 1909, while still a prisoner of the United States at Fort Sill, Oklahoma.
