Jon Hendricks (born September 16, 1921) is an American jazz lyricist and singer. He is considered one of the originators of vocalese, which adds lyrics to existing instrumental songs and replaces many instruments with vocalists (such as the big-band arrangements of Duke Ellington and Count Basie). Furthermore, he is considered one of the best practitioners of scat singing, which involves vocal jazz soloing. For his work as a lyricist, jazz critic and historian Leonard Feather called him the "Poet Laureate of Jazz", while Time dubbed him the "James Joyce of Jive". Al Jarreau has called him "pound-for-pound the best jazz singer on the planet—maybe that's ever been".
