Jackie Mittoo (Donat Roy Mittoo, Browns Town, Saint Ann Parish, Jamaica, 3 March 1948 — Toronto, Ontario, Canada, 16 December 1990) was a Jamaican organ, piano and keyboard player, songwriter and musical director. Keyboard virtuoso Jackie Mittoo was among the true legends of reggae -- a founding member of the Skatalites and an extraordinarily prolific songwriter, he was perhaps most influential as a mentor to countless younger performers, primarily through his work as the musical director at the famed Studio One.
