Michael Been (March 17, 1950 – August 19, 2010) was an American rock musician who achieved critical attention and rotation play on MTV in the 1980s with his band The Call. He later released an album of his solo work and toured with his son's band Black Rebel Motorcycle Club. His song "Let the Day Begin" was the official campaign song of Al Gore's 2000 U.S. presidential campaign. His song "Oklahoma" was one of the top ten choices for Oklahoma's official state rock song and a line from the song provided the name for Another Hot Oklahoma Night: A Rock & Roll Exhibit at the Oklahoma History Center.

Born in Oklahoma City, Oklahoma, Been later lived in Chicago, where he was a member of the band Aorta at the time of their second album Aorta 2, in 1970. He then joined Lovecraft, the successor band to the psychedelic rock group H.P. Lovecraft. He also played with former Moby Grape members Jerry Miller and Bob Mosley in the band Fine Wine, and with Miller in the Original Haze. Been also played bass on the first two albums by 2nd Chapter of Acts, their 1974 album With Footnotes and their 1975 album In the Volume of the Book, as well as Barry McGuire's 1974 release, Lighten Up.
