Queanbeyan (pronounced /ˈkwiːnbiən/) is a regional centre in the Southern Tablelands in south-eastern New South Wales adjacent to the Australian Capital Territory. The city's mixed economy is based on light construction, high technology, manufacturing, service, retail and agriculture. It is the council seat of the Queanbeyan City Council. In 2006, Queanbeyan had a population of 34,084 people.

Following the founding of Canberra, Australia's federal capital, just 15 kilometres (9.3 mi) west, Queanbeyan has become an integral part of the capital city's economy. The word Queanbeyan is the anglicised form of 'Quinbean' - an Aboriginal word meaning "clear waters".

The town grew from a squattage held by ex-convict and inn keeper, Timothy Beard, on the banks of the Molonglo River in what is now Oaks Estate. The town centre of Queanbeyan is located on the Queanbeyan River, a tributary of the Molonglo River and about one mile east of Oaks Estate.

Queanbeyan was officially proclaimed a township in 1838 when the population was about 50. The local parish was also known by that name and later still the member for the electorate of Queanbeyan held a seat in the legislative assembly of the colony of NSW. On 28 November 1837 the Colonial Secretary announced the appointment of Captain Alured Tasker Faunce as resident police magistrate at Queanbeyan. His homestead, called Dodsworth, was situated on the banks of the Queanbeyan river opposite the town.
