Mason Jennings (born March 19, 1975 in Honolulu, Hawaii) is an American pop-folk singer-songwriter. He is well known for his simple yet catchy melodies, intimate lyrics, literary and historical themes, and distinctive voice. His music has appeared in the surf film Shelter and he has toured extensively.

Born in Hawaii, Jennings moved with his family to Pittsburgh, Pennsylvania, at an early age. Jennings learned to play guitar at the age of 13, when he began writing songs. Jennings later dropped out of school and moved to Minneapolis, Minnesota to pursue his musical career.

Jennings produced his self-titled debut album in 1997 on an analog four-track in the living room of a rented home, playing all instruments himself. In October 1998, joined by drummer Chris Stock (a.k.a. Chris Stocksmith) and bassist Robert Skoro, he began a weekly gig at Minneapolis' 400 Bar as the Mason Jennings Band. The two week gig ended up lasting four months. In April, 1999, six months after forming, The Mason Jennings Band and Mason were voted by the 1999 "Picked to Click Poll" conducted by Minneapolis newspaper, City Pages. Mason began touring nationally and expanded the depth of his sound by inviting saxophonist Chris Thomson to play with them occasionally and replacing Stock with Brazilian jazz drummer Edgar Olivera.
