1972–73 Yugoslav First Basketball League

The 1972–73 Yugoslav First Basketball League season was the 29th season of the Yugoslav First Basketball League, the highest professional basketball league in SFR Yugoslavia.

The league expanded from 12 to 14 teams. In addition to regular promotion (winners of the Yugoslav Second Basketball League's east and west divisions, respectively, Kombinat Servo Mihalj Zrenjanin and KK Bosna), the extra two new teams were added via a 4-team round-robin play-in tournament consisting of the bottom two 1971–72 Yugoslav First Basketball League teams (KK Željezničar Karlovac and Oriolik Slavnoski Brod) as well as the second placed teams from the Yugoslav Second Basketball League's east and west divisions, respectively (Mladost Zemun and Željezničar Sarajevo). Held in Sombor during early May 1972, the league expansion play-in tournament was won by Željezničar Karlovac and Željezničar Sarajevo.
