Robert "Bobby" McFerrin Jr. (born in Manhattan, New York, on March 11, 1950) is a jazz-influenced a cappella vocal performer and conductor. He is best known for his 1988 hit song "Don't Worry, Be Happy".

McFerrin is known for his singing technique. Using his unusually large vocal range of four octaves, in many performances he switches rapidly fluidly between normal and falsetto registers to create polyphonic effects, effectively performing both the main melody and the accompanying parts of songs. He makes use of vocal percussion created both with his mouth and by tapping on his chest. McFerrin is also capable of throat singing — a practice common in central Asian regions such as Tuva and Tibet — in which the singer excites the natural overtones from the fundamental vocal pitch, producing a two-or three-part chord of notes from one voice.

A notable document of McFerrin's approach to singing is his 1984 album The Voice, the first solo vocal jazz album recorded with no accompaniment or overdubbing.
