George Treweek (31 March 1905 – 28 October 1991) was an Australian rugby league footballer of the 1920s and 30s. He was a towering second-row forward for his time who formed an integral part of the champion South Sydney Rabbitohs teams of the 1920s and early 1930s. He is rated as one of the finest second-row forwards ever to play for Australia.
Starting out as a fullback in the lower grades, Treweek was moved into the second-row upon reaching first grade and won six premierships with South Sydney, captaining the side in the 1931 and 1932 premiership victories. All up Treweek played 120 games for Souths between 1926 to 1934.
He made 7 Test appearances for the Australian national representative side. His test debut was against the touring Great Britain team in 1928. He was selected to go on the 1929–30 Kangaroo tour of Great Britain, playing in four tests and 22 games in all and scoring six tries. Treweek also played eighteen games for NSW.
Treweek retired quietly at the end of 1934. He never had the heart to tell the press of the day that they had spelled his name wrong throughout his entire career. The proper spelling of his surname is actually Treweeke and not Treweek though he graciously accepted Treweek throughout his life until his death in 1991.
In 2004 he was named by the Souths in their South Sydney Dream Team, consisting of 17 players and a coach representing the club from 1908 through to 2004. In 2006 he was inducted into the ARL Hall of Fame.
In February 2008, Treweek was named in the list of Australia's 100 Greatest Players (1908–2007) which was commissioned by the NRL and ARL to celebrate the code's centenary year in Australia.
