1963 Yugoslav First Basketball League

The 1963 Yugoslav First Basketball League season was the 19th season of the Yugoslav First Basketball League. The season ended with OKK Beograd winning the league championship, ahead of KK Partizan.

The season began during June 1963 following the end of the 1963 FIBA World Championship in Brazil where the Yugoslav national team won silver, its first-ever medal at the FIBA World Championship. The national team success led to an increased level of interest in basketball throughout the country as the public eagerly awaited another showdown between the main title contenders — OKK Beograd led by twenty-four-year-old power forward Radivoj Korać and KK Olimpija whose on-court leader was twenty-five-year-old point guard Ivo Daneu.
