Curtis Michael "Curt" Hennig (March 28, 1958 – February 10, 2003), also known by the ring name Mr. Perfect, was an American professional wrestler who wrestled for, among other promotions, the American Wrestling Association (AWA), World Championship Wrestling (WCW) and the World Wrestling Federation (WWF). He was the son of wrestler Larry "The Axe" Hennig, and father to current WWE superstar Joe Hennig (Curtis Axel.)

Described by WWE as "one of the best in-ring technicians of his generation", Hennig held fifteen championships in various promotions throughout his career. Among other accolades, he is a two-time world champion: one-time AWA World Heavyweight Champion and one-time WWC Universal Heavyweight Champion, two-time WWF Intercontinental Champion, one-time WCW United States Champion, and two-time world tag team champion: one-time AWA World Tag Team Champion (with Scott Hall) and one-time WCW World Tag Team Champion (with Barry Windham). One of the greatest Intercontinental Champions of all time, Hennig was the longest-reigning champion of the 1990s and has been credited with helping bring the importance of the Intercontinental Championship close to that of the WWF Championship during the decade. Although back problems prevented Hennig from being pushed as WWF Champion, he became one of the promotion's most colorful personalities and later assumed a role as a manager and color commentator. In addition to championship success in WCW in the late 1990s, he was also a member of the New World Order and later, wrestling stable and country music group, West Texas Rednecks, who recorded their infamous, tongue-in-cheek song, "Rap is Crap." Hennig returned to the WWF for a brief period in 2002, being one of the last three men remaining at that year's Royal Rumble. He later wrestled for Total Nonstop Action Wrestling (TNA), challenging for the NWA World Heavyweight Championship, prior to his death on February 10, 2003.

Hennig was inducted into the WWE Hall of Fame in 2007 by longtime friend Wade Boggs.
