John Hopoate (born 16 January 1974) is a former professional rugby league footballer, and boxer.
A Tonga, Australia and New South Wales State of Origin representative winger, he played in the NRL for Sydney clubs, the Manly-Warringah Sea Eagles (with whom he won the 1996 Premiership), Wests Tigers and the Northern Eagles.
Hopoate also became the Australian Heavyweight Boxing Champion.
He was born in Tonga, but moved to Australia with his family while he was still young and took up the game of rugby league.
Hopoate began his professional league career with Manly-Warringah while he was nineteen years of age, and was also selected for the Tonga national team.
Hopoate did not play as a regular first-grade player until two years later in 1995 where he showed his ability by scoring 21 tries, finishing second in the top try-scoring table to teammate Steve Menzies.
After many controversies his reputation became greatly tarnished and his career continued on a downhill slide, seeing him become the "most suspended player of the modern era".
In 2018 he was given a 10-year ban from any involvement in rugby league.
Hopoate was also a professional boxer.
He is the father of Canterbury-Bankstown Bulldogs player Will Hopoate.
