Billy Hart (born November 29, 1940) is an American jazz drummer and educator. He is known internationally for his work with Herbie Hancock‘s “Mwandishi” band in the early 1970s, as well as with Shirley Horn, Stan Getz, and Quest, among many others.

Hart was born in Washington, D.C. He grew up in close proximity of the Spotlite Club, where he first heard the music of Lee Morgan, Ahmad Jamal, and Miles Davis, among others.

Early on in his career he performed with Otis Redding and Sam and Dave, then with Buck Hill. Although he studied mechanical engineering at Howard University, he left school early to tour with Shirley Horn, whom Hart credits with accelerating his musical development. He was a sideman with the Montgomery Brothers(1961), Jimmy Smith (1964–1966), and Wes Montgomery (1966–68). Following Montgomery’s death in 1968, Hart moved to New York City, where he recorded with McCoy Tyner, Wayne Shorter, Joe Zawinul, and Pharoah Sanders (playing on his famed recording Karma in 1969), in addition to playing with Eddie Harris, Joanne Brackeen, and Marian McPartland.
