Stalag 17 is a 1953 war film which tells the story of a group of American airmen held in a German World War II prisoner of war camp, who come to suspect that one of their number is an informant. It was adapted from a Broadway play.

Produced and directed by Billy Wilder, it starred William Holden, Don Taylor, Robert Strauss, Neville Brand, Harvey Lembeck, and Peter Graves (Strauss and Lembeck both appeared in the original Broadway production); Wilder also cast Otto Preminger in the role of the camp's Commandant.
