The Frogmen is a 1951 American black-and-white World War II drama film from Twentieth Century Fox, produced by Samuel G. Engel, directed by Lloyd Bacon, that stars Richard Widmark, Dana Andrews, and Gary Merrill.

The film's storyline is based on operations by United States Navy Underwater Demolition Teams, popularly known as "frogmen", against the Japanese Army and naval forces.

Following the opening credits, The Frogmen has an on-screen written statement: "This is a true story based on incidents which occurred in the latter part of World War II.

The unit's men are distrustful of the professionally aloof Lawrence, and the relationship immediately takes a turn for the worse when they brawl with sailors aboard their transport ship.

Pete Vincent, understands the natural resentment the elite UDT men feel over the death of Cassidy, which they have transferred to Lawrence, and offers to go easy on the team at captain's mast.

The "by-the-book" Lawrence, however, elects to hold his own mast and disciplines the entire team just before a dangerous reconnaissance mission to ascertain the safest landing beach during an upcoming invasion of a Japanese-held island.

Lawrence is scornfully perceived as afraid when he splits up the platoon and puts team executive officer Lt. Klinger in charge of a diversion to the more dangerous beach, where the main landing is scheduled.

Lawrence sees that two frogmen, including Chief Jake Flannigan, are still in the water, but rather than risk loss of the information already gathered, orders a rescue boat launched and continues back to the transport.

Several major studios were interested in producing films about the Underwater Demolition Teams, but only Twentieth Century-Fox obtained an exclusive guarantee of cooperation from the U.S. Navy.

The program was directed by Roy Del Ruth and starred Ralph Meeker (Lawrence), James Whitmore (Flannigan), and Richard Arlen (Vincent).
