Early Career
Born and raised in Liverpool, England, Callum Smith grew up surrounded by boxing as part of the famous Smith brothers. His brothers Paul, Stephen, and Liam all pursued professional boxing careers, creating a competitive environment that pushed Callum to excel from a young age.
He developed his skills as an amateur boxer and was working toward Olympic qualification before deciding to turn professional in 2012 after missing out on a spot at the London Olympics. His family’s deep roots in the sport provided the perfect foundation, and he trained extensively before making his professional debut under the guidance of respected trainer Joe Gallagher.
Professional Career

Signing with Eddie Hearn’s Matchroom Sport, Smith quickly showed he was special, winning his first 14 fights with most coming by knockout. His breakthrough moment came in 2015 when he demolished Rocky Fielding in just the first round to capture the British super-middleweight title.
Smith continued his impressive run, winning the WBC Silver title and defending it multiple times. His career peaked in 2018 when he entered the World Boxing Super Series tournament, ultimately defeating George Groves via seventh-round knockout in Saudi Arabia to win the WBA (Super) and Ring magazine super-middleweight titles.
Smith successfully defended these titles against John Ryder in a controversial unanimous decision in 2019. However, he suffered his first professional loss in December 2020 against Canelo Álvarez, losing all his titles despite fighting with a detached left bicep injury. After that setback, Smith moved up to light-heavyweight in 2021, making a statement with a brutal second-round knockout of Lenin Castillo. He’s since rebuilt his career at the higher weight class and captured the WBO interim light-heavyweight title in February 2025.
