Roger Dean Miller (January 2, 1936 – October 25, 1992) was an American singer, songwriter, and musician.

Born in Fort Worth, Texas, to mother Laudene Holt Miller and father Jean Miller, Roger, the youngest of three boys, was sent to live with his uncle and aunt, Elmer and Armelia Miller, in Erick, Oklahoma, when his father died while Roger was just one year old.

Roger had a lonely and unhappy childhood. Heavily influenced by the Grand Ole Opry on Saturday nights and the Light Crust Doughboys on Fort Worth radio, he desperately wanted to be a singer-songwriter. When he was 17 he stole a guitar, but turned himself in and chose to join the army rather than go to jail. He later quipped "My education was Korea, Clash of 52."

On leaving the army he went to Nashville, to work on his music career. In 1959 he wrote his first number one song, "Billy Bayou" recorded by Jim Reeves.
