Henry Doyle Haynes (July 27, 1920 – August 7, 1971) was an American comedy entertainer and musician who gained fame on radio and television as a country and jazz guitarist and as the character Homer of the country music comedy and parody duo Homer and Jethro with Kenneth C. Burns for 35 years beginning in 1936.

Known as Junior and Dude (pronounced "dood'-ee"), the duo was rechristened Homer and Jethro when WNOX Program Director Lowell Blanchard forgot their nicknames during a 1936 broadcast.

In 1947, the duo moved to Cincinnati, Ohio and were working at WLW-AM on the station's Midwestern Hayride.

The pair was fired along with several other stars by new management at WLW in 1948 and, after a brief tour, they moved to Springfield, Missouri and performed on KWTO-AM with Chet Atkins, the Carter Family and Slim Wilson.

He and Burns were inducted into the Country Music Hall of Fame in 2001 as Homer and Jethro.
