New Caledonia (ˌkælᵻˈdoʊniə ; Nouvelle-Calédonie nuvɛl kaledɔni) is a sui generis collectivity of overseas France in the southwest Pacific Ocean, south of Vanuatu, about east of Australia, and from Metropolitan France. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre "Le Caillou" ("the pebble").
New Caledonia has a land area of divided into three provinces. The North and South Provinces are on the New Caledonian mainland, while the Loyalty Islands Province is a series of three islands off the east coast of mainland. New Caledonia's population of 271,407 (October 2019 census) is of diverse origins and varies by geography; in the North and Loyalty Islands Provinces, the indigenous Kanak people predominate, while the wealthy South Province contains significant populations of European (Caldoches and Metropolitan French), Kanak, and Polynesian (mostly Wallisian) origin, as well as smaller groups of Southeast Asian, Pied-Noir, and North African heritage. The capital of New Caledonia is Nouméa.
New Caledonia was part of the continent Zealandia, which broke off from the supercontinent Gondwana between 79 million and 83 million years ago. The earliest traces of human presence in New Caledonia date back to the period when the Lapita culture was influential in large parts of the Pacific, 1600–500 BCE or 1300–200 BCE. The Lapita were highly skilled navigators and agriculturists. The first settlements were concentrated around the coast and date back to the period between c. 1100 BCE to 200 CE.
British explorer James Cook was the first European to sight New Caledonia, on 4 September 1774, during his second voyage. He named it "New Caledonia", as the northeast of the island reminded him of Scotland.
