The 2009–10 BBL season of the British Basketball League (BBL) was the 23rd season since the league's establishment in 1987. The regular season commenced on 25 September 2009, when Milton Keynes Lions claimed the first win of the season with a 94–81 victory in the opening game against Worcester Wolves. A total of 13 teams took to the court including new start-up franchise Essex Pirates, which was founded by Great Britain Under 20s coach Tim Lewis, and a newly rebranded Rocks team carrying the name of the city of Glasgow instead of their previous Scottish Rocks title. The League Championship came down to the final game of the season and was only claimed by Newcastle Eagles after Sheffield Sharks lost their last game, 97–95, to Worthing Thunder. Thunder's Evaldas Zabas' basket four seconds from the end meant that Newcastle had won the League even before taking to the court the following day. Everton Tigers concluded the season with victory in the play-offs despite being the lowest seed in all of their Play-off encounters. An 80–72 win against Glasgow in the final gave Tigers their first ever Play-off title, only two years after its foundation in 2007.
