Olympic City Giants were a professional basketball team based in Oldham, England. Previously based in Bolton and Bury, the team were known as Bolton & Bury Hawks and then Bolton & Bury Giants, the team were founder members of the British Basketball League in 1986.
After an eighth-place finish in the 1987–88 Carlsberg League campaign, Giants qualified for their first and only BBL-era Play-off. They drew top seed Glasgow Rangers, and were soundly beaten in both games of the bet-of-three series by the regular season Champions.
In 1988 after encountering several financial difficulties, Olympic City Giants formally merged with Manchester Eagles (formerly Manchester United) to become Manchester Giants, marking a return of the famous name after a three-year absence, following a merger between the original Manchester Giants and Manchester United in 1985.
