2023–24 National Basketball League (England) season

The 2023–24 National Basketball League (NBL) season in England was a season of competition in the National Basketball League, the second tier of British basketball below the British Basketball League (BBL). The league is administered by Basketball England.

The season featured teams across multiple divisions, including Division One (the highest level of the NBL), Division Two, Division Three, and Division Four, each with its own regional structure. Teams competed in a regular season format, with games played both home and away. At the conclusion of the regular season, teams qualified for playoffs based on their league standings.

The playoffs determined the league champions for each division. Promotion and relegation between divisions occurred at the end of the season, based on performance and subject to Basketball England's regulations and approvals regarding facilities and financial viability. Key aspects of the season included player statistics, game results, league tables, and notable player performances. Teams typically featured a mix of British and international players. The season also served as a platform for player development and scouting opportunities for the BBL.

Changes to league rules, team participation, and sponsorship could occur from season to season. Information on specific champions and relegated/promoted teams can be found from Basketball England's website or dedicated basketball news sources.
