Cooma is a town in the south of New South Wales, Australia. It is located 114 kilometres (71 mi) south of the national capital, Canberra, via the Monaro Highway. It is also on the Snowy Mountains Highway, connecting Bega with the Riverina.

At the 2021 census, Cooma had a population of 6,715. Cooma is the main town of the Monaro region. It is 800 metres (2,620 ft) above sea level. The name could have derived from an Aboriginal word Coombah, meaning 'big lake' or 'open country'.

Cooma is 5 kilometres (3 mi) south of the banks of the Murrumbidgee River, a main tributary of the Murray–Darling basin. Cooma sources its water from the river.

The area now known as Cooma lies on the traditional lands of the Ngarigo people.

Cooma was explored by Captain J. M. Currie in 1823. It was first surveyed in 1840, and was gazetted in 1849. Cooma was proclaimed a municipality in 1879.

The railway from Sydney was extended from Royalla to Cooma in 1889 under the supervision of John Whitton. The line was closed to rail passenger traffic in 1989. The estimated population of Cooma was 47 in 1851 and it grew to 2330 (1911), 1969 (1933), 2249 (1947), 9103 (1966), 7353 (1976) and 7978 (1981).

In 1949, the town became the headquarters of the Snowy Mountains Scheme and grew rapidly. Between 1949 and 1974 the population expanded due to an influx of 65,000 workers from more than 30 countries. Those working on the Snowy Scheme depended on the railway and during construction of the scheme, the railways were one of the largest employers in the region. In 1959, the tenth anniversary of the scheme was celebrated with the erection of an avenue of flags representing the 27 nationalities of people working on the scheme.

Cooma has developed a growing tourism industry as it became the main rest stop for many travellers heading to the NSW snow fields during the winter months. As a result, the town nicknamed itself the 'Gateway to the Snowy Mountains'.

The Aviation Pioneers' Memorial at Cooma contains artifacts recovered from the Avro 618 Ten aircraft Southern Cloud, which crashed on 21 March 1931 in the Toolong range of the Australian Alps. The wreck was not found until 26 October 1958.

Cooma has a number of heritage-listed sites, including:

• Bradley Street: Cooma railway station
• 59–61 Lambie Street: Royal Hotel
• Sharp Street: Rock Bolting Development Site

Cooma has a dry oceanic climate (Cfb). Summer averages are warm, though tend to swing wildly between hot and cool; and winters are chilly with particularly cold night time temperatures due to its valley location, high elevation, and frequent clear skies, sometimes recording the lowest temperatures in the country. However, daytime maximum temperatures in winter are often unremarkable, on account of the foehn effect.

The area is exceptionally dry by southeast coastal Australian standards as it lies in a major rain shadow; the region is flanked by mountain ranges on all sides, most notably on the west. Despite its dryness, it has only 90.1 clear days annually, lower than the adjacent coastal areas of Wollongong and Sydney (106 and 107 clear days respectively). Strong cold fronts often push through the region in winter and snow is not uncommon in Cooma from June to September, though is generally light and rarely settles for more than 24 hours. Frost occurs in all months of the year and is frequent between April and October. Severe thunderstorms are semi-frequent in summer, and owing to the elevation of the town can carry large quantities of hail.

Mean daily minimum temperatures range from −2.7 °C (27.1 °F) (July) to 10.8 °C (51.4 °F) (January), with an annual mean daily minimum of 4.1 °C (39.4 °F). Mean daily maximum temperatures range from 11.4 °C (52.5 °F) (July) to 27.3 °C (81.1 °F) (January), with an annual mean daily maximum of 19.4 °C (66.9 °F).

The airport is located at a higher elevation than the town, causing maximum temperatures to be notably cooler but minima somewhat milder.

The Cooma–Monaro Time Walk in Centennial Park was a community project to mark the Bicentennial Year of 1988, from designs by Cooma College of TAFE and the Cooma–Monaro Historical Society.
