Wellington ( /ˈwɛlɪŋtən/) is the capital city and second most populous urban area of New Zealand. It is at the southwestern tip of the North Island, between Cook Strait and the Rimutaka Range. It is home to 393,400 residents.

The Wellington urban area is the major population centre of the southern North Island, and is the seat of the Wellington Region – which in addition to the urban area covers the Kapiti Coast and Wairarapa. The urban area includes four cities: Wellington, on the peninsula between Cook Strait and Wellington Harbour, contains the central business district and about half of Wellington's population; Porirua on Porirua Harbour to the north is notable for its large Māori and Pacific Island communities; Lower Hutt and Upper Hutt are largely suburban areas to the northeast, together known as the Hutt Valley. Wellington also holds the distinction of being the world's most southerly capital city.
