Sahara is a 1943 American action war film directed by Zoltán Korda and starring Humphrey Bogart as an American tank commander in Libya who, along with a handful of Allied soldiers, tries to defend an isolated well with a limited supply of water from a Libyan Afrika Korps battalion during the Western Desert Campaign of World War II.

The story is based on the novel Patrol by Philip MacDonald, and an incident depicted in the 1936 Soviet film The Thirteen by Mikhail Romm. The adaptation is by John Howard Lawson, who later was a member of the blacklisted Hollywood Ten. Sahara was remade by André de Toth as a Western called Last of the Comanches (1953), and four decades later by Brian Trenchard-Smith as the American-Australian television film Sahara (1995). Nine Men, released by Ealing Studios on 22 February 1943, has a similar basic plot line.

Critics praised the film for its blend of action, suspense and poignancy. J. Carrol Naish earned an Oscar nomination for Best Supporting Actor, Rudolph Maté was nominated for Best Cinematography (Black-and-White), and John Livadary was nominated for Best Sound.
