Guy Charles Clark (November 6, 1941 – May 17, 2016) was an American Texas country and folk singer, musician, songwriter, recording artist, and performer. He released more than twenty albums, and his songs have been recorded by other artists including Jerry Jeff Walker, Jimmy Buffett, Lyle Lovett, Ricky Skaggs, Steve Wariner, and Rodney Crowell. He won the 2014 Grammy Award for Best Folk Album: My Favorite Picture of You.

Clark was born in Monahans, Texas, and eventually settled in Nashville, where he helped create the progressive country and outlaw country genres. His songs "L.A. Freeway" and "Desperados Waiting for a Train" that helped launch his career were covered by numerous performers. The New York Times described him as "a king of the Texas troubadours", declaring his body of work "was as indelible as that of anyone working in the Americana idiom in the last decades of the 20th century".
