Enzo Maccarinelli (born 20 August 1980) is a Welsh former professional boxer who competed from 1999 to 2016. He held the WBO cruiserweight title from 2006 to 2008, and the European and British cruiserweight titles between 2010 and 2012.
On 8 July 2006, Maccarinelli fought against former World Boxing Council (WBC) cruiserweight champion Marcelo Fabian Domínguez for the WBO interim cruiserweight title. Maccarinelli won the title with a ninth-round TKO. The natural progression was a title fight against the then WBO title holder, Johnny Nelson. Due to several injuries to Nelson this matchup never transpired, and on 22 September 2006 he announced his retirement, automatically relinquishing the belt and allowing Maccarinelli to be promoted to full champion status. *
