Gift Horse (released in the United States as Glory at Sea) is a 1952 British black-and-white World War II drama film. It was produced by George Pitcher, directed by Compton Bennett, and stars Trevor Howard, Richard Attenborough, James Donald, and Sonny Tufts.

The film follows the story of the fictional ship HMS Ballantrae and her crew from the time they come together in 1940 until they go on a one-way mission to destroy a German-held dry dock in France. The final mission is based on HMS Campbeltown and the St Nazaire Raid. The title is a reference to the old proverb "Never look a gift horse in the mouth".
