George Treweek was an Australian rugby league footballer who played in the 1920s and 1930s. He was a towering second-row in his time, who formed an integral part of the champion South Sydney teams of the 1920s and early 1930s. He is rated as one of the finest second-row forwards ever to play for Australia. George Treweek came to Souths from Grahamstown near Tumut after playing in a trial against a visiting Mascot team.

They called George Treweek ''Arms and Legs'' because of his wild and ungainly running style, but it was those same limbs that wrought havoc on the football fields of Australia and England. Treweek stood 188cm, making him the tallest player of his era and his ability to split the defence made him one of the game's great second-rowers.

Starting out as a fullback in the lower grades at the Mascot Juniors RLFC, Treweek was moved into the second-row upon reaching first grade and won five premierships with South Sydney, captaining the side in the 1931 and 1932 premiership victories. Treweeke proved his stamina and determination captaining Souths in the 1930s and his reputation as an attacking forward is legendary. All up Treweek played 120 games for Souths between 1926 and 1934.

Despite his destructive nature on the field, Treweek was a gentle giant off of the field. Treweek worked as a butcher which meant 4am starts and on match days he would be serving customers until midday before gathering his gear and heading off to the game.

He made seven 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. On the Kangaroo tour of 1929–30 the English press described him as the greatest forward in the world.

Currently he is listed on the Australian Players Register as kangaroo No. 142. Treweek also played eighteen games for NSW. He retired gracefully, not having the heart to tell the press George Treweeke was born Albert George Treweek. The family name was always spelled without the final ‘E’. His brothers and parents all kept the original spelling but George changed it to Treweeke. 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 Treweek not Treweeke, though he graciously accepted Treweeke throughout his life - a gentleman to the end.

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) by the NRL and ARL to celebrate the code's centenary year in Australia. George died in 1991 aged 86.
