The Basketball League of Serbia (Serbian: Кошаркашка лига Србије / Košarkaška liga Srbije), commonly abbreviated as KLS, is a top-tier men's professional basketball league in Serbia. Founded in 2006. It is currently not run by the Basketball Federation of Serbia (KSS).[1]
The league, operated by the Basketball Federation of Serbia, consists of two stages: the First League which has 16 teams and the SuperLeague which has 8 teams.
Since the 2017–18 season, the top 8 teams in First League are promoted to Super League with five Serbian teams from the ABA League. Two lowest-placed teams, positioned 15th and 16th in the First League, are relegated to a lower-tier league – Second Basketball League of Serbia. Teams positioned 1st and 2nd in First League will be qualified for the next season's ABA League Second Division. The SuperLeague has 8 clubs divided into 2 groups of 4 teams. The best 4 clubs (top 2 teams from groups A and B each) in the SuperLeague go to the Playoff stage.
