King Kolax (born William Little, November 6, 1912 – December 18, 1991)[1] was an American jazz trumpeter and bandleader.

Around 1938, he became bandleader of one of the groups; this ensemble toured the U.S. and continued playing regularly at venues such as the Savoy Theater and the 65 Club.

[2] Kolax made regular engagements at hotels and ballrooms throughout the 1950s in Chicago and elsewhere; he had a working relationship with Sun Ra, who wrote arrangements for him.

[2] Kolax had a position in the Chicago Federation of Musicians, and union rules prevented him from performing and holding office simultaneously.

He retired around 1981 and died in Chicago ten years later after suffering from Alzheimer's disease for an extended period.
