William McKinney (17 September 1895 – 14 October 1969) was an American jazz drummer who led a series of musical groups, most notably McKinney's Cotton Pickers.

William "Bill" McKinney was born in Cynthiana, Kentucky. He worked as a drummer in a circus band, then after serving in the United States Army in World War I settled in Springfield, Ohio where he took over leadership of the Synco Jazz Band. After hiring drummer Cuba Austin, McKinney worked as leader and business manager. After touring the U.S. Midwest, they got a residency at the Arcadia Ballroom in Detroit, Michigan in 1926. In Detroit they were heard by bandleader and music promoter Jean Goldkette, who arranged a more lucrative home base for the band in Detroit's Graystone Ballroom. The band was renamed McKinney's Cotton Pickers.
