The 2001–02 BBL season was the 15th season in the history of the British Basketball League. The regular season ran from September 27, 2001, to March 31, 2002, whilst the post-season Play-offs culminated with the Grand Final at Wembley Arena on April 27. Chester Jets claimed a famous "clean-sweep" by winning all three BBL competitions as well as the ntl:home National Cup. Jets' head coach Robbie Peers was awarded the League's Coach of the Year accolade whilst John Thomas, also of the Jets, claimed that Player of the Year award.

London Towers represented the United Kingdom in Europe's most prestigious competition, the Euroleague, however the capital-based team came up against giants Kinder Bologna, FC Barcelona and Union Olimpija in Group B and eventually finished with a 0-14 record. Birmingham Bullets made a brief appearance in the North European Basketball League.

The Manchester Giants franchise, once one of the League's title contenders, were withdrawn from the BBL midway through the season by League officials following ongoing financial difficulties. Prior to withdrawing in December, the Giants had a 2-7 record in the Northern Conference.
