Grassella Oliphant (September 1, 1929, Pittsburgh) is an American jazz drummer. Oliphant backed Ahmad Jamal in 1952 and Sarah Vaughan in the late 1950s, then worked with Gloria Lynne and Shirley Scott. He released two soul jazz albums as a leader on Atlantic Records in the 1960s. The Grass Roots, released in 1965, saw Oliphant working with saxophonist Harold Ousley, vibraphonist Bobby Hutcherson, and bassist Major Holley. His 1968 release The Grass Is Greener featured John Patton on organ, Grant Green on guitar, and Clark Terry on trumpet, in addition to Ousley and Holley again. The Grass Is Greener has been repeatedly sampled by hip hop artists. Both albums were reissued on CD by Collectables Records as a single disc in 2005. After an almost 40-years hiatus from music, working as the manager of a golf course, Oliphant resumed playing in the 2000s, this time in the New Jersey area.
