Rollerball is a 1975 dystopian science fiction sports film directed and produced by Norman Jewison. It stars James Caan, John Houseman, Maud Adams, John Beck, Moses Gunn and Ralph Richardson. The screenplay, written by William Harrison, adapted his own short story "Roller Ball Murder", which had first appeared in the September 1973 issue of Esquire.

Although Rollerball had a largely American cast, a Canadian director, and was released by the American company United Artists, it was produced in London and Munich.

Rollerball was a box office success, and critical reviews were initially mixed but have warmed somewhat over time.
