List of current world boxing champions

Since at least John L. Sullivan, in the late 19th century, there have been world champions in professional boxing. The first of today's organizations to award a world title was the World Boxing Association (WBA), known as the National Boxing Association (NBA), when it sanctioned its first title fight in 1921 between Jack Dempsey and Georges Carpentier for the world heavyweight championship.

There are now four major sanctioning bodies in professional boxing. The official rules and regulations of the World Boxing Association,World Boxing Council (WBC),International Boxing Federation (IBF), and World Boxing Organization (WBO) all recognize each other in their rankings and title unification rules. Each of these organizations sanction and regulate championship bouts and award world titles. American boxing magazine The Ring began awarding world titles in 1922.

There are seventeen weight divisions. To compete in a division, a boxer's weight must not exceed the upper limit. Manny Pacquiao has won world championships in eight different weight divisions, more than any other boxer. The Klitschko brothers, Vitali and Wladimir, held all four major titles in the heavyweight division from 2011 to 2013; they were the first brothers to hold versions of the heavyweight championship at the same time.

When a champion, for reasons beyond his control such as an illness or injury, is unable to defend his title within the normal mandatory time, the sanctioning bodies may order an interim title bout and award the winner an interim championship. The WBA and WBC may change the status of their inactive champions to Champion in Recess.

The World Boxing Association (WBA) was founded in 1921 as the National Boxing Association (NBA), a national regulating body of the United States. On August 23, 1962, the NBA became the WBA, which today has its head office in Panama. According to WBA championship rules, when a champion also holds a title of one of the other three major sanctioning bodies in an equivalent weight division, that boxer is granted a special recognition of "Unified Champion", and is given more time between mandatory title defences. The WBA Championships Committee and President may also designate a champion as a "Super Champion" or "Undisputed Champion" in exceptional circumstances; the standard WBA title is then vacated and contested between WBA-ranked contenders. When a WBA "Regular Champion" makes between five and ten successful defences, he may be granted the WBA "Super" title upon discretion of a vote of the WBA's board of governors.
