ACT and Southern NSW Rugby Union

The ACT and Southern NSW Rugby Union is the governing body for rugby union in the Australian Capital Territory and southern regions of New South Wales.

The union is represented by one team in the Super Rugby competition, the Brumbies. The ACT is also home to the Canberra Vikings in the National Rugby Championship.

The union was founded in 1937 as the Federal Capital Territory Rugby Union (FCTRU). It became the ACTRU in 1939, and eventually the ACT and Southern NSW Rugby Union. It received its current name prior to the 2005 Super 12 season, when the Far South Coast and Southern Inland unions of New South Wales joined the ACT and Monaro Rugby Unions. This change also led to the former ACT Brumbies being renamed Brumbies Rugby.
