Williamson was previously the European super-middleweight champion from December 2025 to January 2026 and held the British light-middleweight title between October 2021 and December 2022. As an amateur, Williamson won the 2015 ABA Championships in the middleweight division.
Troy Williamson was born on 22 August 1991 in Darlington, England. The fourth youngest of 11 children, he first began boxing at the age of 10. As the age for participating in competitive fights is 11, he quickly became bored of the training regime and walked away from the sport. He regained interest at the age of 17, going on to compile a record of 68âÂÂ15. During his amateur career he reached the finals of two ABA Championships; losing against Anthony Fowler at the 2014 edition and winning the competition the following year. He also represented England at the 2015 European Championships, losing in the quarter-finals, and competed at the 2015 and 2016 World Series of Boxing as part of the British Lionhearts.
Williamson made his professional debut on 29 October 2016, scoring a third-round knockout victory over Borislav Zankov at the Meadowbank Sports Centre in Edinburgh, Scotland. After compiling a record of 12âÂÂ0âÂÂ1 (9 KOs) he faced Dario Socci for the vacant IBF European junior-middleweight title on 21 December 2019 at the Copper Box Arena in London. Williamson captured his first professional title by defeating Socci via technical knockout (TKO) in the tenth and final round.
He won the British light-middleweight title by knocking out defending champion Ted Cheeseman in the 10th round at Liverpool Arena on 9 October 2021.
Despite being knocked to the canvas in the second round, Williamson successfully defended the title with a unanimous decision win over Mason Cartwright at Newcastle Arena on 25 March 2022.
Back at the same venue, he lost the championship in his second defense against Josh Kelly on 2 December 2022, going down to a unanimous decision defeat.
Williamson was due to face English super-middleweight champion Mark Dickinson at Rainton Meadows Arena in Houghton-le-Spring on 6 September 2025, but his opponent failed to make the required weight and was stripped of the title. The fight went ahead with only Williamson now able to claim the vacant championship, and he did just that by stopping Dickinson in the ninth round.
He challenged European, British and Commonwealth super-middleweight champion Callum Simpson at First Direct Arena in Leeds on 20 December 2025. Williamson sent Simpson to the canvas four times in the 10th round and won via technical knockout when the referee waived the fight off following the fourth knock down.
Without making any defenses,Williamson vacated the European super-middleweight title on 26 January 2026 after Simpson invoked a rematch clause in their original fight contract. This was due to European Boxing Union rules which forbid direct rematches, forcing him to give up the championship.
