Trapped is a 1949 American film noir crime film directed by Richard Fleischer and starring Lloyd Bridges, Barbara Payton, and John Hoyt. It was written by George Zuckerman and Earl Felton.

Like many semidocumentaries, the film begins with a voice over footage of the treasury department, telling the story of what the department does. Then it quickly begins the story once a woman tries to deposit a $20 bill at the bank that turns out to be phony.
