The youngest boxing undisputed four-belt world champion is Devin Haney (USA, b. 17 November 1998), who was aged 23 years 200 days when he became the undisputed men’s lightweight world champion on 5 June 2022 in Melbourne, Victoria, Australia.
Haney became the first undisputed men’s lightweight champion in the four-belt era (WBC, WBA [Super], WBO and IBF) when he outpointed George Kambosos Jr at Marvel Stadium in Melbourne. Teófimo López had previously claimed to be the undisputed lightweight champion but he held only the “franchise” version of the WBC belt, while Haney had retained its regular version.
