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

Breaking down every boxing champion in each division.

Today's era in boxing recognizes four different sanctioning bodies as having the legitimacy to crown world champions. In order of their age of recognition in the sport, the WBA, WBC, IBF and WBO crown title holders in seventeen weight divisions (The WBA and WBC also recognize the bridgerweight division). This is a massive expansion from the original eight glamour divisions that each only had one champion. It's why becoming a multi-weight title holder has lost some of it's luster (Adrien Broner anyone?). In addition to this, The Ring magazine crowns a champion as well. This titleholder is internationally recognized in most circles as the lineal champion of the division.

Diehard and casual boxing fans have often listed the proliferation of more belts and world titles up there with too many PPV's and bad judging as their chief complaints. In fact, most full time boxing journalists can't name the IBF champion in the flyweight division without looking it up. Spoiler, it's vacant. This is to say nothing about the plethora of regional, international, and interim title holders. And as if things couldn't get any more confusing, different sanctioning bodies actually have different names for the same weight classes. For example, the WBA refers to the 154 pound division as super welterweight where as the IBF refers to it as junior middleweight. For this reason, the weight limits are listed next to their respective divisions.

It is nearly a weekly occurrence that world title belts are vacated, interim champions elevated, champions stripped and unification fights won. This list is meant to provide a current look at all the champions across every weight class recognized by the four sanctioning bodies. For levity, interim champions are omitted. Special shout out to Japan, in large part because of two guys named Inoue, they control all the world titles in both junior featherweight and bantamweight.
