Joseph Arthurlin "Joe" Harriott (15 July 1928 in Kingston, Jamaica – 2 January 1973 in Southampton, Hampshire) was a Jamaican jazz musician and composer, whose principal instrument was the alto saxophone.
Initially a bebopper, he became a pioneer of free-form jazz. He was educated at Kingston's famed Alpha Boys School, which produced a number of prominent Jamaican musicians. He moved to the UK as a working musician in 1951 and lived in the country for the rest of his life. Harriott was part of a wave of Caribbean jazz musicians who arrived in Britain during the 1950s, including Dizzy Reece, Harold McNair, Harry Beckett and Wilton Gaynair.
