David Alan Heath (born February 10, 1976) is an American mixed martial artist, currently competing in the light heavyweight division of the Ultimate Fighting Championship, where he made his debut at UFC 62 , defeating Cory Walmsley by first-round submission.

Heath extended his UFC record to 2-0 in December 2006 in a victory over Canadian Victor Valimaki at UFC Fight Night 7 in San Diego.Heath lost to Lyoto Machida at UFC 70, and was a replacement for Machida's original opponent, Forrest Griffin, who withdrew from the bout due to a nagging staph infection.

Heath fought Renato Sobral at UFC 74. Sobral defeated Heath by anaconda choke in the second round. Sobral continued to hold the choke for four seconds after Heath tapped out, which is illegal, and ignored the commands of referee Steve Mazzagatti, who tried to physically break the hold.

Renato stated during the post-fight interview that "He (Heath) has to learn respect. He deserved that. He called me 'mother fucker'." Sobral also disregarded the boos from the over 11,000 fans, saying "The crowd didn't like it? Who cares? At least they had a reaction."
