Merrill's Marauders is a 1962 Technicolor war film, photographed in CinemaScope, and directed and co-written by Samuel Fuller. It is based on the exploits of the long-range penetration jungle warfare unit of the same name in the Burma campaign, culminating in the Siege of Myitkyina.

The source is the nonfiction book The Marauders, written by Charlton Ogburn Jr., a communications officer who served with Merrill's Marauders. Filmed on location in the Philippines, the economical historical epic film stars Jeff Chandler (in his final role) as Frank Merrill and several actors from the Warner Bros. Television stock company, who were then the lead actors in American television shows. The supporting cast features Ty Hardin from Bronco, Peter Brown from Lawman, Andrew Duggan from Bourbon Street Beat, and Will Hutchins from Sugarfoot.
