The 2020–21 Basketball League of Serbia (Serbian Cyrillic: Кошаркашка лига Србије 2020–21.) is the 15th season of the Basketball League of Serbia, the top-tier professional basketball league in Serbia. Also, it's the 77th national championship played by Serbian clubs inclusive of the nation's previous incarnations as Yugoslavia and Serbia & Montenegro.
The season is the first to be played after the previous season was abandoned due to the COVID-19 pandemic in Serbia. The Basketball Federation of Serbia ruled that the 13 teams from the previous season will stay in the league and the three highest-placed clubs from Second League will be promoted. The first-placed team from the previous season, Borac, joins the ABA League. Crvena zvezda mts is the defending champion.
The First League began on 25 September 2020. The SuperLeague will start in May 2021.
