David Michael Terrell (born January 9, 1978) is an American mixed martial artist from Santa Rosa, California. A black belt in Brazilian Jiu-Jitsu under Cesar Gracie, no one has scored a point against Terrell in a grappling match (though he is not undefeated in the sport). He has fought as a middleweight in the Ultimate Fighting Championship before being released from his contract.
In his UFC debut, he scored a stunning knockout victory over top middleweight Matt Lindland. The victory instantly thrust Terrell into title contention, as his next fight was against Evan Tanner for the vacant UFC Middleweight Championship title in February 2005. Despite locking Tanner in a tight guillotine choke, Terrell lost the hold and eventually lost the match by technical knockout in the first round.
Plagued by recurring injuries, Terrell's next fight did not come until UFC 59 in April 2006, where Terrell submitted his opponent, Scott Smith, with a rear naked choke in the first round. Controversy surrounds the victory, though, as questionable officiating by referee Marco Lopez led Smith to file a complaint to the California State Athletic Commission.  At UFC 62 he was supposed to fight Yushin Okami but withdrew the bout due to a sinus infection. The fight with Okami was then rescheduled to UFC 66, but Terrell again pulled out of the fight citing an elbow injury suffered during training. 
Despite an early report which claimed that Terrell was planning to move to light heavyweight,  Terrell was scheduled to fight Ed Herman in a middleweight contest at UFC 78 in November 2007.  However, he was dropped from the card due to injury. Canadian Joe Doerksen took his place against Ed Herman.
