Giacobbe Fragomeni (born 13 August 1969) is an Italian professional boxer. He held the WBC cruiserweight title from 2008 to 2009, and previously the European Union cruiserweight title from 2007 to 2008. As an amateur he won a bronze medal at the 1997 World Championships and gold at the 1998 European Championships, both in the heavyweight division. Outside of boxing, Fragomeni won the 2016 edition of the Italian reality TV show L'Isola dei Famosi.
Fragomeni made his professional debut on 19 May 2001, winning a four-round points decision against Henry Kolle Njume. Having won his next twenty fights, Fragomeni lost for the first time against European cruiserweight champion (and future heavyweight world champion) David Haye on 17 November 2006. This was a grudge match from their amateur days, as Fragomeni had defeated Haye in the final qualifiers for the 2000 Olympics. Fragomeni bounced back by winning the vacant European Union cruiserweight title with a unanimous decision (UD) over Vincenzo Rossitto on 31 July 2007, and went on to make two successful defences.
