Heavyweight

No upper limit

The marquee division. Heavyweight has no upper weight limit (the WBC introduced a 224-pound "bridgerweight" class below it in 2020). The four-belt era of heavyweight unification was opened in 1999 when Lennox Lewis became undisputed champion. In May 2024 Oleksandr Usyk became the first undisputed four-belt heavyweight champion of the modern era by outpointing Tyson Fury.
