Stephen Collins (born 21 July 1964, Cabra, Dublin, Ireland), more commonly known as Steve Collins, is an Irish professional boxer. Known as the "The Celtic Warrior", Collins is the former WBO middleweight and super-middleweight champion.
Collins began his professional career in America, and lost two world title fights on points. It was not until Collins reached his 30's that he fulfilled his potential. Having competed against the best boxers on both sides of the Atlantic, Collins tends to be linked more to the era in the UK when there was a great rivalry between British boxers Chris Eubank and Nigel Benn. He fought and beat both, twice.
