Bronco Banyon McKart (born March 20, 1971) is an American former professional boxer who competed from 1992 to 2014. He held the WBO light middleweight title in 1996 and is best known for his trilogy of fights against Winky Wright.
Nicknamed "Superman", McKart turned pro in 1992 and captured the WBO Light Middleweight Title in 1996 by beating Santos Cardona by TKO. He lost the title in his first defense to Winky Wright. In 2000, he had the opportunity to avenge the loss by taking on Wright in an eliminator for IBF Light Middleweight Title. Wright won a dominant decision. In 2002, the two re-matched again, this time for Wright's IBF Light Middleweight Title. McKart was disqualified after trailing severely in the fight.
In 2004, he took on WBA Light Middleweight Title holder Travis Simms, but lost a decision. In 2006, he was knocked out by the then undefeated prospect Kelly Pavlik. He fought Anthony Mundine at the Palms Casino Resort on 14 July 2012. McKart retired in 2014.
