David Samuel Pike (March 23, 1938 – October 3, 2015) was a jazz vibraphone and marimba player. He appears on many albums by Nick Brignola, Paul Bley and Kenny Clarke, Bill Evans, and Herbie Mann. He also recorded extensively as leader, including a number of albums on MPS Records.

He learned drums at the age of eight and was self-taught on vibes. Pike made his recording debut with the Paul Bley Quartet in 1958. He began putting an amplifier on his vibes when working with flautist Herbie Mann in the early 1960s. By the late 1960s, Pike’s music became more exploratory, contributing a unique voice and new contexts that pushed the envelope in times remembered for their exploratory nature. Doors of Perception, released in 1970 for the Atlantic Records subsidiary Vortex Records and produced by former boss Herbie Mann, explored ballads, modal territory, musique concrète, with free and lyrical improvisation, and included musicians like alto saxophonist Lee Konitz, bassist Chuck Israelsand pianist Don Friedman.
