Verboten! is a 1959 American romantic war drama film written, produced and directed by Samuel Fuller and starring James Best, Susan Cummings, Tom Pittman, and Harold Daye. It was the last film of the influential but troubled RKO Radio Pictures studio, which co-produced it with Fuller's own Globe Enterprises. It was filmed at the RKO Forty Acres backlot. Distribution was handled by Columbia Pictures.

Verboten! was the first of Samuel Fuller's films to be set during World War II, of which he was a veteran. He had previously drawn on his war experience to make movies about the Korean War and the French Indochina War. Raymond Harvey was the film's technical adviser; he had previously worked with Fuller on his Fixed Bayonets! (1951).
