Nouméa (French pronunciation: [numea]) is the capital and largest city of the French special collectivity of New Caledonia. It is situated on a peninsula in the south of New Caledonia's main island, Grande Terre, and is home to the majority of the island's European, Polynesian ( Wallisians, Futunians, Tahitians), Indonesian, and Vietnamese populations, as well as many Melanesians, Ni-Vanuatu and Kanaks who work in one of the South Pacific's most industrialised cities. The city lies on a protected deepwater harbour that serves as the chief port for New Caledonia.
At the September 2019 census, there were 182,341 inhabitants in the metropolitan area of Greater Nouméa ( French: agglomération du Grand Nouméa), 94,285 of whom lived in the city ( commune) of Nouméa proper.  67.2% of the population of New Caledonia live in Greater Nouméa, which covers the communes of Nouméa, Le Mont-Dore, Dumbéa and Païta.
The first European to establish a settlement in the vicinity was British trader James Paddon in 1851. Anxious to assert control of the island, the French established a settlement nearby three years later in 1854, moving from Balade in the north of the island. This settlement was initially called Port-de-France and was renamed Nouméa in 1866. The area served first as a penal colony, later as a centre for the exportation of the nickel and gold that was mined nearby.
During World War II, Nouméa served as the headquarters of the United States military in the South Pacific. The five-sided U.S. military headquarters complex was adopted after the war as the base for a new regional intergovernmental development organisation: the South Pacific Commission, later known as the Secretariat of the Pacific Community, and later still as the Pacific Community.
The city maintains much of New Caledonia's unique mix of French and old Melanesian culture. Even today the US wartime military influence lingers, both with the warmth that many New Caledonian people feel towards the United States after experiencing the relative friendliness of American soldiers and also with the names of several of the quarters in Nouméa. Districts such as "Receiving" and "Robinson", or even "Motor Pool", strike the anglophone ear strangely, until the historical context becomes clear.

- 6e km, 7e km, Normandie, and Tina

- Ducos, Ducos industriel, Kaméré, Koumourou, Logicoop, Numbo, Tindu

Although Nouméa has more sunshine days than any other Pacific Island capital and beaches not far from the city centre, it is not currently a major tourist destination.
Nouméa is, as of 2007 [update], one of the most rapidly growing cities in the Pacific and has experienced a major housing construction boom in the preceding decade. The installation of amenities has kept pace and the municipality boasts a public works programme.
Aircalin, the international airline of New Caledonia,  and Air Calédonie (Aircal), the domestic airline, have their headquarters in the city.  Aircal's headquarters are on the grounds of Nouméa Magenta Airport,  which serves local routes. Nouméa's international airport is La Tontouta International Airport, 50 kilometres (31 mi) from the city.
The Nouméa-Païta railway, which was the only railway line that ever existed in New Caledonia, was closed in 1940.
The University of New Caledonia (UNC) goes back to 1987 when the Université Française du Pacifique (French University of the Pacific) was created, with two centres, one in French Polynesia and the other in New Caledonia. In 1997 the decision was made to split the two parts into separate universities and so in 1999 the Université de la Nouvelle Calédonie and the Université de la Polynésie Française were formed.
UNC welcomes around 3,000 local and international students and 100 professors and researchers each year. 
The Bibliothèque Bernheim (Bernheim Library) is located in Nouméa.
