Marc Copland (born May 27, 1948, as Marc Cohen, in Philadelphia, Pennsylvania) is an American jazz pianist and composer.

Copland became part of the jazz scene in Philadelphia in the early 1960s as a saxophonist, and later moved to New York where he experimented with electric alto saxophone. In the early 1970s, while pursuing his own harmonic concept, he grew dissatisfied with what he felt were inherent limitations in the saxophone and moved to the Baltimore-Washington D.C. area, where he remained for a decade to retrain as a jazz pianist.
