Super League Basketball (SLB) is a men's professional basketball league. Established in 2024, the competition replaces the former British Basketball League (BBL) as the top-level men's basketball competition in Great Britain.
From 1987, the British Basketball League (BBL) was the pre-eminent basketball competition in Great Britain. By 2024, Basketball League Ltd (BLL), the operating company behind the BBL, was in severe financial difficulties. Due to this uncertainty, the British Basketball Federation (BBF) terminated BLL's operating license to run the men's professional league, with immediate effect. On the same day a new organisation, Premier Basketball Limited, was formed by a consortium of existing basketball teams formerly of the BBL. The consortium, led by Sarah Backovic, director of Sheffield Sharks, was granted a three-year license by the BBF to operate the top-level men's basketball competition, in place of the former BBL.
On 2 August, Super League Basketball was announced as the name for the new competition.
