Jack Garratt (born 11 October 1991) is a British singer and multi-instrumentalist from Little Chalfont, Buckinghamshire. He released his debut studio album Phase on 19 February 2016.

His mother was a primary school music teacher and his father was a police officer. He grew up in the village of Little Chalfont. About his childhood he has stated that: "I just really enjoyed making noises and really enjoyed the reaction that I got from making those noises. So they [parents] put me on music lessons to encourage me to hone in on that talent rather than show off." He wrote his first song when he was 12 and learned to play a variety of instruments from the guitar, drums and piano to the harmonica, mandolin, trombone and ukulele. He attended St. Clement Danes secondary school in Chorleywood. He later attended the University of Roehampton, in London.
