Nouméa (numea) is the capital and largest city of the French special collectivity of New Caledonia and is also the largest francophone city in Oceania. 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 (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. Eager 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.
From 1904 to 1940, Nouméa was linked to Dumbéa and Païta by the Nouméa-Païta railway, the only railway line that ever existed in New Caledonia.
During World War II, the United States Navy built Naval Base Noumea and 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.
