List of Spanish basketball champions

The Spanish basketball champions are the winners of the main basketball competition in Spain, which since 1983–84 is the Liga ACB. The league is contested on a round robin basis and the championship awarded to the team that is top of the league at the end of the season. The Liga Nacional, first established in 1957, originally contained six teams. Before the league, the Copa del Rey—a regionalised cup competition—was effectively the national championship. Nowadays, Liga ACB is contested by 18 teams; the two lowest-placed teams are relegated to the LEB Oro and replaced by the top two teams in that division. Of the founding teams in the league, only Estudiantes, Joventut and Real Madrid have not been relegated.
