Khartoum is a 1966 British epic war film written by Robert Ardrey and directed by Basil Dearden. It stars Charlton Heston as British General Charles "Chinese" Gordon and Laurence Olivier as Muhammad Ahmed, with a supporting cast that includes Richard Johnson and Ralph Richardson. The film is based on historical accounts of Gordon's defence of the Sudanese city of Khartoum from the forces of the Mahdist army, during the 1884–1885 Siege of Khartoum. The opening and closing scenes are narrated by Leo Genn.

Robert Ardrey was an American playwright, screenwriter and science writer perhaps best known for The Territorial Imperative (1966). After a Broadway and Hollywood career, he returned to his academic training in anthropology and the behavioral sciences in the 1950s.
