1989–90 British Basketball League season
The 1989–1990 BBL season was the third season of the British Basketball League since its establishment in 1987. The season featured a total of just eight teams, playing 28 games each. Due to the low number of teams, the post-season play-offs featured only the top four teams from the regular season instead of the usual top eight finishers.
The future of the league was in the balance due to the waning number of teams. Livingston folded, Crystal Palace and Hemel Hempstead Watford Royals both dropped to the National League and Glasgow Rangers moved back to Kingston. There was small consolation in the formation of a new club called London Docklands which joined the league.
Kingston completed a clean sweep of all four trophies claiming the title and Play-off crown, as well as the National Cup and NatWest League Trophy.
Oldham Celtics secured the second tier league title for a second consecutive year.Final standings
