Cruiserweight (boxing)

Cruiserweight, also referred to as junior heavyweight, is a weight class in professional boxing between light heavyweight and heavyweight. Before the advent of the current cruiserweight class, "light heavyweight" and "cruiserweight" were sometimes used interchangeably in the United Kingdom.

Professional boxing

The current weight limit for the division is. When originally established, the weight limit was. The division was established in order to accommodate smaller heavyweight boxers who could not compete with the growing size of boxers in that division. While many great heavyweight champions weighed around 190 pounds during their careers, during the 1970s it became fairly standard that fit heavyweight boxers weighed at least. Many boxing authorities felt that asking men weighing between and to fight these larger men was unfair.
The North American Boxing Federation was the first sanctioning body to recognize the cruiserweight division when it sanctioned a bout between Marvin Camel and Bill Sharkey for its version of the title on June 5, 1979. Camel won the match, which led to the World Boxing Council sanctioning its first cruiserweight title fight between Marvin Camel and Mate Parlov on December 8, 1979. That fight was a draw, but in the rematch in March 1980 Camel won and became the first cruiserweight champion. In 1982 the World Boxing Association recognized Ossie Ocasio as its first cruiserweight champion when he defeated South African Robbie Williams. The International Boxing Federation followed suit in 1983 when it matched former WBC champion Marvin Camel against Rick Sekorski for its inaugural title. Camel won and became the first IBF cruiserweight champion.
Several boxers moved up to heavyweight after winning world titles at cruiserweight. Evander Holyfield unified the WBA, WBC, and IBF titles to become undisputed champion, the first to do so, and then moved up to the heavyweight division in 1988. In 2006, the second man to become undisputed champion was O’Neil Bell, who was later stripped of the IBF title. Oleksandr Usyk became undisputed cruiserweight champion in 2018; he moved to heavyweight in 2019, becoming the undisputed champion in 2024.
Other notable champions in the division have been Bobby Czyz, Dwight Muhammad Qawi, Tomasz Adamek, Virgil Hill, Al Cole, Orlin Norris, James Toney, David Haye, and Tony Bellew.
