The middleweight division, from 154 to 160 lbs, has long been one of the most popular in professional boxing. The origins of the weight class can be traced back to the 1840s during the bare-knuckle era of the sport. Gennady ‘Triple G’ Golovkin is regarded as the best middleweight in the world at the moment and that’s backed up by the numerous titles he holds.
Some of the greatest boxers in history have fought as middleweights including Jake LaMotta, Sugar Ray Robinson, Carmen Basilio, Dick Tiger, Emile Griffith, Carlos Monzon, Marvin Hagler, Roberto Duran, Sugar Ray Leonard, Tommy Hearns, Felix Trinidad, Roy Jones Jr., Oscar De La Hoya and Bernard Hopkins.
This list consists of the 10 longest single reigns in the weight division in one or more of the sport’s governing bodies such as the IBF, WBA, WBC, WBO, and IBO. If a boxer was champion more than one time then his longest reign is considered rather than combined reigns as middleweight champ.
