The 1989–90 Crvena zvezda season is the 45th season in the existence of the club.

The team played in the Yugoslav Federal A League and the FIBA Korać Cup.

Guards Nebojša Ilić and Saša Obradović, and forward Slobodan Kaličanin were ruled out for the season due to the compulsory military service in the Yugoslav People's Army.

Youth players Dragan Aleksić, Mirko Pavlović, Dušan Stević, Mlađan Šilobad, and Časlav Trifunović were promoted from the junior selection.
