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 January 1879, during the Anglo-Zulu War. Some 150 British soldiers at a remote outpost, 30 of whom were sick and wounded, held off a force of 4,000 Zulu warriors.

The film was directed and co-written by American screenwriter Cy Endfield. He had moved to the United Kingdom in 1951 for work after being blacklisted in Hollywood. It was 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 Stanley 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 Mangosuthu Buthelezi (a future South African political leader) played Zulu King Cetshwayo kaMpande, who was his great-grandfather. The opening and closing narration is spoken by Richard Burton.

The film was first shown on the 85th anniversary of the battle, 22 January 1964, at the Plaza Theatre in the West End of London. Zulu received widespread critical acclaim, with praise for the sets, soundtrack, cinematography, action sequences, and the cast's performances, 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 as the 93rd best British film ever.
