The First Federal Basketball League (Serbo-Croatian: Prva savezna košarkaška liga) was the highest tier level men's professional club basketball competition in the former country of SFR Yugoslavia. Founded in 1945, and folded in 1992 (1991–92 Winer Broker YUBA League), it was run by the Basketball Federation of Yugoslavia. With a total of 16 European-wide trophy winners and 11 finalists, the Yugoslav First Basketball League was one of the strongest European national domestic basketball leagues of all time.
