UFC 37: High Impact was a mixed martial arts event held by the Ultimate Fighting Championship at the CenturyTel Center in Bossier City, Louisiana on May 10, 2002.

The event was seen live on pay per view in the United States, and was later released on home video.

The card was headlined by a Middleweight Title Bout between Murilo Bustamante and Matt Lindland.

Bustamante had Lindland hooked cleanly in an armbar early in the fight, then released it after what seemed to be a tap, followed by a shout to stop the action by John McCarthy.

Bustamante was stripped of the title in October 5, 2002 after signing with PRIDE, thereby vacating the UFC Middleweight Championship belt.
