Richard Hawn (born September 15, 1976), known as Rick Hawn, is a former Olympic judoka and professional mixed martial artist. A professional MMA fighter from 2009 to 2015, Hawn most notably competed for Bellator MMA, where he won the Bellator Season 6 Lightweight Tournament and the Bellator Season 9 Welterweight Tournament.

Hawn was born in Chicago, but when he was young, his family moved to Eugene, Oregon. At age 12, Hawn began training in judo when his father got back into the sport. Hawn continued to compete while attending South Eugene High School, where he also competed in wrestling, and also football in his senior year.

In 1996, after graduating from high school, Hawn qualified to live at the Olympic Training Center in Colorado Springs, Colorado. There, he trained in judo for eight years and ultimately qualified for the 2004 Olympic Games. At the Games in 2004, Hawn went 2-2 and finished in 9th place. Hawn also won numerous medals at the U.S. national championships and two medals at the Pan American Games.

After the 2004 Games, Hawn moved to Boston to train with bronze medalist Jimmy Pedro. However, Hawn failed to make the 2008 Olympic judo team. Soon after, Hawn began training for a career in Mixed Martial Arts.

Hawn's professional mixed martial arts debut came in January 2009 in Worcester, Massachusetts. Hawn won by a technical knockout in the first round. Over the next two years, Hawn won his next eight fights, six by TKO.

In March 2011, Hawn began competing in the Bellator MMA's Season Four Welterweight Tournament. He defeated Jim Wallhead by a unanimous decision in the quarterfinals and Lyman Good by a split decision in the semifinals.

Hawn was defeated by Jay Hieron at Bellator 43 in a fight which some believe was a controversial split decision.

After a strong showing in the Season Four Tournament, Hawn was planning to return to the cage as part of Bellator's Season Five Welterweight Tournament, but an injury during training forced him out of the tournament.
