Konstantin Borisovich "Kostya" Tszyu (/ˈkɒstə ˈzuː/; Russian: Константин Борисович «Костя» Цзю, IPA: [kənstɐnʲˈtʲin bɐˈrisəvʲɪtɕ ˈkosʲtʲə ˈdzːʲu]; born 19 September 1969) is a Soviet-born Australian former professional boxer who competed from 1992 to 2005. He held multiple light-welterweight world championships, including the undisputed and lineal titles between 2001 and 2005. Tszyu was an exceptional all-around boxer-puncher who relied heavily on accuracy and timing, and carried formidable punching power; he is often regarded as one of the hardest-punching light-welterweights in the division's history.
