"Who's Cheatin' Who" is the title of a country music song written by Jerry Hayes and initially recorded by Charly McClain. It was the title track of her 1980 album for Epic Records, released in November 1980 as a single with "Love Scenes" on the B-side, and in early 1981, was her first Number One hit on the Billboard country charts. Seventeen years later, Alan Jackson had chart success with the song as well, with his cover version reaching Top Five on the country charts.
