Queanbeyan (/ˈkwiːnbiən/ KWEEN-bee-ən) is a city in south-eastern New South Wales, Australia, located adjacent to the Australian Capital Territory in the Southern Tablelands region.

Canberra, Australia's capital, is located 15 kilometres (9 miles) to the west, and Queanbeyan is a commuter town.

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 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.

Queanbeyan became an increasingly successful primary producing district, and was proclaimed a Municipality in February 1885 incorporating an area of 5,700 acres (23 km2).

William James Farrer, the wheat experimentalist, established Queanbeyan's reputation as an agricultural district with his famous "Federation" rust-free strain, developed on his property "Lambrigg" at Tharwa.

At the height of its rural prosperity Queanbeyan boasted sixteen public houses and six flourmills powered by wind, water, horse and steam.

From 1982 to 1989, the Canberra Raiders rugby league team played their home games in Queanbeyan, at Seiffert Oval.

The Queanbeyan District Hospital is a small but modern facility providing Maternity, Emergency and some Community Health services.

After police operations at 8 Farrer Place were moved to temporary accommodation in Morisset Street, the old station, opened in July 1978, was demolished starting in February 2019.

In February, the Queanbeyan Showground plays host to the annual "Convoy for Kids" to aid cancer research.

Federally, Queanbeyan lies within the electorate of Eden-Monaro, currently held by Kristy McBain representing the Australian Labor Party.

At a state level, Queanbeyan is the major population centre in the seat of Monaro, held by Steve Whan of the New South Wales Labor Party since May 2023.
