The League of Communists of Kosovo (Serbo-Croatian: Savez komunista Kosova, Савез комуниста Косова, SKK/СКК; Albanian: Lidhja e Komunistëve të Kosovës) was the Kosovo branch of the League of Communists of Yugoslavia, the sole legal party of Yugoslavia from 1945 to 1990.

The status of an honorary autonomous province was presented to ethnic Albanian communists who helped the Yugoslav partisans in their struggles during World War II, carved out from the section of the former Ottoman province within the Socialist Republic of Serbia (i.e. whilst one chunk of the former province was given to Albania in 1912, the other sections of it were awarded to Yugoslavia's newly created republics: Montenegro and Macedonia).

From its creation, Kosovo's administration lacked real power.

During the early 1990s, growing ethnic tensions between the republics of Yugoslavia led to the breakup of the federal party — the Kosovo Communists wanted to upgrade Kosovo from an autonomous republic within Serbia to the 7th socialist republic of Yugoslavia, with the same status of Croatia, Montenegro, Bosnia, Macedonia, Slovenia and Serbia proper.

On October 12, 1990, it ceased to exist due to amendments to the constitution reverting Kosovo to its pre-1974 status by Slobodan Milosević.
