Zulu is a 1964 British epic adventure action war film depicting the Battle of Rorke's Drift between a detachment of the British Army and the Zulu in 1879, during the Anglo-Zulu War, in which 150 British soldiers, 30 of whom were sick and wounded, at a remote outpost, held off a force of 4,000 Zulu warriors.

The film was directed by American screenwriter Cy Endfield and produced by Stanley Baker and Endfield, with Joseph E. Levine as executive producer. The screenplay was by Endfield and historical writer John Prebble, based on Prebble's 1958 Lilliput article "Slaughter in the Sun". The film stars Baker and introduces Michael Caine, in his first major role, with a supporting cast that includes Jack Hawkins, Ulla Jacobsson, James Booth, Nigel Green, Paul Daneman, Glynn Edwards, Ivor Emmanuel, and Patrick Magee. Zulu chief and future South African political leader Mangosuthu Buthelezi played Zulu King Cetshwayo kaMpande, his great-grandfather. The opening and closing narration is spoken by Richard Burton.

The film was first shown on the 85th anniversary of the actual battle, 22 January 1964, at the Plaza Theatre in the West End of London. Zulu received widespread critical acclaim, with praise going to the sets, soundtrack, cinematography, action sequences and the performances of the cast, particularly Baker, Booth, Green and Caine. The film brought Caine international fame. In 2017 a poll of 150 actors, directors, writers, producers, and critics for Time Out magazine ranked it the 93rd best British film ever.
