#1 Jeremy Stephens (14 losses)
Poor Jeremy Stephens. The MMA star has an unwelcome record to his name as the fighter who has lost more times in UFC than any other martial artist.
Stephens entered the UFC with a loss in his debut bout versus Din Thomas at UFC 71 on May 26, 2007. The American has never been able to put together a run of victories ever since then in his long 11-year career with the promotion.
It may surprise many that Stephens has never been cut considering he has never been a contender for a Championship. However, Stephens, despite his less than stellar win/loss record inside the Octagon is an exciting fighter, proven by the fact that he has won "Fight of the Night" and "Knockout of the Night" on many different occasions.
The 32-year-old will likely remain part of UFC for a long time to come, which unfortunately will likely mean he will continue to add to his unfortunate record.
