Douglas Bruce Green (born March 20, 1946), better known by his stage name Ranger Doug, is an American musician, arranger, award-winning Western music songwriter, and Grand Ole Opry member best known for his work with Western music and the group Riders in the Sky in which he plays guitar and sings lead and baritone vocals.

The show features the music of such classic western performers as Gene Autry, Roy Rogers, Tex Ritter, Rex Allen, and the Sons of the Pioneers, as well as more obscure recordings.

Green provides commentary with fellow Rider in the Sky Fred LaBour (stand-up bassist stage-named Too Slim) in the role of Ranger Doug's sidekick, the crusty old trail cook called Sidemeat.

[3] Prior to forming Riders in the Sky, he performed with The Boys from Shiloh, The Shinbone Alley All Stars, and The Doug Green Band.

He recorded two albums in 1972 with Vic Jordan and the Buck White Family, one of gospel songs (In God's Eyes)[4] and one traditional bluegrass named after his daughters Liza Jane and Sally Anne.
