Steve Weisberg (born 1963 in Norfolk, Virginia, United States) is an American composer, pianist, recording artist, and producer.

In the 1980s, after studying with Michael Gibbs at Berklee College in Boston, Massachusetts, he recorded the XtraWatt/ECM release "I Can't Stand Another Night Alone (In Bed With You)," produced by Carla Bley and Steve Swallow, recorded and performed with Karen Mantler and her Cat Arnold, and contributed arrangements for Hal Willner's Lost in the Stars: The Music of Kurt Weill (A&M).

He moved to Los Angeles in 2003, and in 2004 continued to act as musical director/arranger for two Hal Willner events: "Shock & Awe: The Music of Randy Newman," featuring Los Lobos, Howard Tate, Gavin Friday, Victoria Williams, Vic Chesnutt, Stan Ridgway, and Van Dyke Parks, and "Let's Eat: A Tribute to The Firesign Theater," featuring John Goodman, George Wendt, Howard Hesseman, Todd Rundgren, Loudon Wainwright III, Chloe Webb, and David Thomas (Pere Ubu).

In 2007, he acted as musical director and arranger for Perla Batalla's "The Gospel According to Leonard Cohen," an all-star tribute concert in Los Angeles including Jackson Browne, Michael McDonald, Howard Tate, Bill Frisell, and Jill Sobule.

In addition, he produced tracks for 'operapper' Reggie Bennett (a classically trained baritone singer and rapper) creating a new genre combining hip-hop and operatic style singing.
