The Liga ACB (English: ACB League), known as the Liga Endesa (English: Endesa League) for sponsorship reasons, is the first tier level men's professional basketball league in Spain. It began in 1957, with the name of Liga Nacional, and was originally organized by the Spanish Basketball Federation. The league changed to its current form, beginning with the 1983–84 season, after the Asociación de Clubs de Baloncesto (ACB) took control over the league. The league is rated as one of the top three European national domestic/regional leagues in the ULEB League Rankings system.
The ACB League, which is played under FIBA rules, currently consists of 18 teams, including Real Madrid, FC Barcelona Regal, Cajasol Banca Cívica, Asefa Estudiantes, Gran Canaria 2014, Caja Laboral Baskonia, Valencia Basket, and Unicaja Málaga.
