Roy Nelson is an American mixed martial artist who competes in the heavyweight division of the Ultimate Fighting Championship. He won Season 10 of Spike TV's The Ultimate Fighter. The September 30, 2009 broadcast of his fight against Kimbo Slice, officially an exhibition, was the 2nd most-watched MMA match in U.S. history.

He was also the last International Fight League Heavyweight Champion. Nelson started off his martial arts training in Shaolin Kung Fu for a number of years and is a black belt in Brazilian Jiu-Jitsu under Renzo Gracie. Nelson is currently ranked the #10 heavyweight in the world by Sherdog. In his first fight since The Ultimate Fighter Finale, Nelson knocked out Stefan Struve after 39 seconds in the first round at the co-main event of UFC Fight Night 21 on March 31, 2010, winning his second straight Knockout of the Night Bonus. Nelson was scheduled to fight Cheick Kongo, though the bout was cancelled after Kongo withdrew. Nelson instead faced junior dos Santos at UFC 117 in a bout to determine the #1 contender (after Cain Velasquez) to the UFC Heavyweight title. Nelson lost by unanimous decision (30-26, 30-27, 30-27), but was able to withstand the varied attacks of dos Santos, becoming the first man to take dos Santos to a decision. Nelson was scheduled to face Shane Carwin at UFC 125. Carwin, however, had to pull out of the fight due to a back injury. Nelson was pulled off the card altogether.

On November 14, 2010, UFC President Dana White announced that Nelson's UFC career would be on hold due to Nelson being contractually bound to another fight promotion. White declined to specifically name the promotion, but sources close to Nelson confirmed that Roy Jones Jr.'s Square Ring Promotions claimed to have Nelson tied down. Nelson stated on the MMA Hour with Ariel Helwani that this is old news and that he is still able to fight in the UFC with no problems. Nelson faced Frank Mir on May 28, 2011 at UFC 130 and lost by unanimous decision. UFC president Dana White criticized Nelson's performance after the fight for Nelson's lack of conditioning. Nelson blamed a bout with the flu for his poor performance. Nelson indicated that he has plans of cutting weight and fighting in the light heavyweight division at some point in the future.

Nelson faced PRIDE FC legend Mirko Filipovic on October 29, 2011 at UFC 137 and won by TKO in the 3rd Round. Nelson next fought the returning Fabricio Werdum at UFC 143 on February 4, 2012. He lost the fight via unanimous decision. The back and forth action earned Fight of the Night honors.
