Geronimo (full title: Geronimo: The Story of a Great Enemy) is a 1939 American Western film starring Chief Thundercloud as Geronimo, the famous leader of Apache warriors who fought against American colonizers.

This is the first film depiction of Geronimo's life.

The army's effort to capture Apache chief Geronimo, who is leading a band of warriors on a rampage of raiding and murder, is hampered by a feud between two officers—who are father and son.

The film is recognized by American Film Institute in these lists: The exclamation Geronimo!, shouted when jumping from a great height, may have entered the English language through the 1939 film.

During World War II, the film was shown to a group of paratroopers at Fort Benning, Georgia, who afterwards began to shout Geronimo!
