Brian Tennyson (born July 10, 1962) is a retired American golfer.

Tennyson was born in Evansville, Indiana. He played college golf at Ball State University and turned professional in 1984.

When his golf game diminished in 1991 and 1992, Tennyson quit golf and accepted a job in October 1992 as vice president of strategic planning at Papa John's Pizza - he had been roommates with Papa John's founder, John Schnatter at Ball State. He helped take the company public in June 1993. Unhappy with a corporate job, Tennyson quit in April 1994 and decided to resume his golf career. He returned to the PGA Tour in 1996 where he had one top-10 finish, T-9 at the Quad City Classic. He played on the Buy.com Tour (now Web.com Tour) from 1998 to 2000 where his best finish was second at the 1999 Nike Dayton Open.
