Steve Marcus (September 18, 1939^[1] – September 25, 2005)^[2] was an American jazz saxophonist.

Marcus was born in The Bronx, New York, United States.^[1] He studied at the Berklee College of Music in Boston, Massachusetts, between 1959 and 1961.^[1] He gained experience playing in the bands of Stan Kenton, Herbie Mann and Larry Coryell from 1963 to 1973.^[1] His first album as a leader included an arrangement of the Beatles' song, "Tomorrow Never Knows". He worked with jazz drummer Buddy Rich for the last twelve years of Rich's life.^[1] After Rich died, Marcus led the band and renamed it Buddy's Buddies.^[2]

His song "Half a Heart" (1968) has a riff very similar to the famous saxophone riff of "Baker Street" by Gerry Rafferty (recorded in 1977, released in 1978).

Marcus died in September 2005 in New Hope, Pennsylvania.^[2]
