The 1983–84 ACB season was the inaugural season of the ACB Primera División, the top Spanish professional basketball league.
It started on 10 September 1983 with the first round of the regular season and ended on 13 April 1984 with the finals.
[1][2] Real Madrid won their first ACB title, and their 23rd Spanish title after the decision of the Competition Committee, when FC Barcelona didn't appear in the third game of the finals in protest of what it considered an unfair decision by this body following a fight between players in the second game of the finals: Davis was sanctioned for six games due to attack Real Madrid player Iturriaga, who had previously elbowed him in a block.
[4] Another significant change was the introduction of the overtimes in case of draw.
[1] A total of 16 teams contested the league, including 12 sides from the 1982–83 Liga Nacional and four promoted from the 1982–83 Primera División B.
