"David Keith Murray (born February 19, 1955) is an American jazz saxophonist and composer who performs mostly on tenor and bass clarinet. He has recorded prolifically for many record labels since the mid-1970s.

Murray was born in Oakland, California, United States. He attended Pomona College, graduating in 1977. He was initially influenced by free jazz musicians such as Albert Ayler and Archie Shepp. He gradually evolved a more diverse style in his playing and compositions. Murray set himself apart from most tenor players of his generation by not taking John Coltrane as his model, choosing instead to incorporate elements of mainstream players Coleman Hawkins, Ben Webster and Paul Gonsalves into his mature style. Despite this, he recorded a tribute to Coltrane, Octet Plays Trane, in 1999. He played a set with the Grateful Dead at a show on September 22, 1993, at Madison Square Garden in New York City. His 1996 tribute to the Grateful Dead, Dark Star, was also critically well received.

Murray was a founding member of the World Saxophone Quartet with Oliver Lake, Julius Hemphill and Hamiet Bluiett. He has recorded or performed with musicians such as Henry Threadgill, James Blood Ulmer, Olu Dara, Tani Tabbal, Butch Morris, Donal Fox, McCoy Tyner, Elvin Jones, Sunny Murray (no relation), Ed Blackwell, Johnny Dyani, Fred Hopkins, and Steve McCall. David Murray's use of the circular breathing technique has enabled him to play astonishingly long phrases."
