2023–24 ACB season

The 2023–24 ACB season, also known as Liga Endesa for sponsorship reasons, was the 41st season of the top Spanish professional basketball league, since its establishment in 1983. It started on 23 September 2023 with the regular season and ended on 12 June 2024 with the finals.

Barça was the defending champion which was swept in semifinals by Real Madrid in a rematch of last year's finals, with Los Blancos winning a record-extending 37th Spanish title (15th in the ACB era) after another sweep against outstanding UCAM Murcia in the finals.

On May 13, 2023, MoraBanc Andorra became the first team to secured the promotion to ACB after a 95–61 huge win to Club Ourense Baloncesto in the next-to-last round of the regular season that crowned it as LEB Oro champions.
