Complete list of undisputed heavyweight champions: Oleksandr Usyk joins boxing legends such as Muhammad Ali and Mike Tyson

Some of boxing’s greatest-ever have been undisputed heavyweight champions during their career and now Oleksandr Usyk is the latest.
Iconic fighters like Muhammad Ali and Mike Tyson achieved the feat while Sonny Liston, George Foreman and Evander Holyfield have also held all the titles at once.
Ukraine sensation Oleksandr Usyk became the first undisputed heavyweight champion since 1999 following a split-decision win over Tyson Fury in May 2024.
In a fight for the ages, Usyk dropped Fury in the ninth round to wrestling the WBC belt from the Gyspy King to add to his WBA, WBO, and IBF titles that he claimed from Anthony Joshua.
Usyk has since vacated the IBF gold, with Daniel Dubois claiming it before defending the title against Joshua.
Instead of taking on the mandatory challenger, Usyk arranged to fight Fury again and came out on top once more.
Dubois is set to defend his belt against Joseph Parker, with the winner set to face Usyk for the chance to unify the division.
The Ukrainian modern-day boxing legend could easily have decided to call it a day there, but he wants to become undisputed champion for a second time.
Despite no longer being undisputed, Usyk is one of 26 stars who have held all of the heavyweight titles at once with the first-ever undisputed heavyweight champion being Jack Dempsey in 1922.
Dempsey’s reign lasted four years before Gene Tunney took the honour and it changed hands many times over the next two decades.
Joe Louis is the boxer who has been the undisputed heavyweight champion for the longest, sitting at the top of the sport for 12 years.
Rocky Marciano, Joe Frazier, Buster Douglas, Liston, Foreman, Tyson and Ali are all some huge names who have also held all the available titles.
