World women's boxing champions list: WBA, WBO, WBC, IBF and The Ring title holders in every weight class

There are 17 weight classes in professional boxing, and five major recognised belts for each of the divisions: The WBA (World Boxing Association), WBC (World Boxing Council), IBF (International Boxing Federation), WBO (World Boxing Organization) and The Ring.

There are four recognised major bodies in boxing, the WBA, WBC, IBF and the WBO. The Ring title is awarded by American boxing magazine, The Ring, and has been done since 1922.

The mixture of belts and champions means that there is only a rare occasion when a class can be fully unified to produce an undisputed champion.

Boxers often fight across weight classes in order to maximise their chances of success, with boxers stepping up and down various classes.

Here is every champion in each weight class for women's boxing.
