Herbert Clayton "Hank" Penny (September 18, 1918 – April 17, 1992), was an American country singer mainly in the Western swing genre. He blended country and western music with dixieland, swing, and most notably bebop jazz styles, earning the nickname “the king of hillbilly bebop”. He also worked as a comedian best known for his backwoods character "That Plain Ol' Country Boy" on TV with Spade Cooley. Penny was married to country singer Sue Thompson from 1953–63.
