Konstantin Borisovich "Kostya" Tszyu (/ˈkɒstə ˈzuː/; Russian: Константин (Костя) Борисович Цзю; born 19 September 1969) is a Russian-Australian former professional boxer. He is a four-time light welterweight world champion, having also spent a period of time as the undisputed champion of that division. Tszyu was a good all-around boxer, who relied heavily on accuracy and timing with his shots and carried exceptional punching power, often being regarded as one of the hardest-punching light welterweights in the division's history.
Tszyu holds notable victories over former world champions Julio César Chávez, Zab Judah and Roger Mayweather. In November 2001 he became the first champion to unify the light welterweight division in over 30 years, and is considered by many in Australia to be a national sports hero. In The Ring magazine's March 2010 issue, Tszyu was ranked as the number one junior welterweight of the 2000s decade. On 7 December 2010, he was inducted into the International Boxing Hall of Fame for the Class of 2011.
