Jake Mathews (born Jacques Lagrandeur born March 14, 1971, in Sudbury, Ontario, Canada) is a Canadian country music singer, songwriter and performer.

Jake's self-titled debut CD (Jake Mathews) garnered six nationally charted hits: "I’ll Do You One Better," "Try Again Tomorrow," "That's How Long," "Rush," "I’m Gone" and "There Ain't No Such Thing."
