Billy Butler (born June 7, 1945, Chicago, Illinois) is an American soul singer and songwriter active principally in the 1960s and early 1970s.

Butler is Jerry Butler's younger brother. He formed the vocal group The Enchanters while at high school. He first recorded for Okeh Records in 1963, and was produced initially by Curtis Mayfield and later by Carl Davis. On early recordings he was backed by The Chanters, a renamed version of the Enchanters; other members were Errol Batts and Jesse Tillman. His first and biggest hit was 1965's "I Can't Work No Longer", which reached #6 on the U.S. Billboard Black Singles chart and #60 on the Billboard Hot 100. The group disbanded in 1966, and after a minor solo hit with "The Right Track" he left Okeh.
