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

Although conventionally grouped with "Country" singers, Miller's unique style defied easy classification. He had a string of pop hits in the 1960s, and also his own TV show for a few years. Many of his recordings were humorous novelty songs with whimsical lyrics, coupled with vocalese riffs filled with nonsense syllables. Others were sincere ballads, which also caught the public's fancy, none more so than his signature song, "King of the Road", about a presumed "hobo" who relishes his life and freedom, riding the rails.

In addition to 11 Grammy Awards, Roger Miller won Broadway's Tony award for writing the score for the musical Big River.

He was voted into the Nashville Songwriters Hall of Fame in 1973 and the Country Music Hall of Fame in 1995.
