Undisputed Boxing Champion
The fighter who simultaneously holds world championships from all of the main sanctioning bodies is considered the indisputable champion of a weight class in professional boxing. The WBA, WBC, IBF, and WBO are currently the four main sanctioning organizations. Before there were four sanctioning bodies in 2007, there were many uncontested champions, but there have only ever been 13 boxers to simultaneously hold all four belts.
As of December 2022, the undisputed champions in the super middleweight, light middleweight, lightweight, and bantamweight divisions are Canelo Álvarez, Jermell Charlo, Devin Haney, and Naoya Inoue, respectively.
