Lewis Crocker (born 6 January 1997) is a Northern Irish professional boxer. He has held the IBF welterweight title since 2025.
Lewis also won the WBO European welterweight title in 2020 and held the WBA Continental European Title after defeating Tyrone McKenna in the Battle of Belfast on 2 December 2023.
Crocker faced Paddy Donovan in a final eliminator for the IBF welterweight title on 1 March 2025 at SSE Arena in Belfast, Northern Ireland. Donovan knocked Crocker to the canvas at the end of the eighth round but was disqualified after the referee ruled the bell had gone before the punch was delivered. He had already been deducted points in rounds six and eight for illegal use of the elbow and head. Donovan appealed against his disqualification and on 27 March 2025, the IBF announced it had granted him a rematch.
The rematch on 13 September 2025 at Windsor Park in Belfast for the vacant IBF welterweight title was a much closer bout than the first. Crocker fought more tactically as a counterpuncher, a style by which he dropped Donovan in rounds three and five en route to a split decision victory, winning the IBF welterweight title.
