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.

After the end of Second World War in Yugoslavia in 1945, there arose a need for athletic development in the fledgling nation.

Post-WW2 Yugoslavia was (with the exception of major cities such as Belgrade, Ljubljana, Zagreb, and Sarajevo) for the most part lacking in competitive opportunities in sports.

After a decade of dominance, the 1980s saw a disappointing slump of talent in the Yugoslav Basketball League.
