Tszyu was born in Sydney, New South Wales, to Russian parents. His father Kostya Tszyu is of ethnic Russian, Korean and Mongolian descent and his mother Natasha Anikina is of ethnic Russian descent. His father, Kostya, is a former undisputed light-welterweight champion who was inducted into the International Boxing Hall of Fame in 2011.

As a soccer player, he was selected to play for multiple local representative teams but his interest in the sport began to wane at the age of 13 when he temporarily relocated to Moscow with his family for a few months before returning to Sydney. At the age of 15, Tszyu decided to quit football and began pursuing a career in boxing.
