Wellington Province, governed by the Wellington Provincial Council, was one of the provinces of New Zealand from 1853 until the abolition of provincial government in 1876. It covered much of the southern half of the North Island until November 1858, when Hawke's Bay Province split off, taking about a third of its area.

Greater Wellington, also known as the Wellington Region, is a non-unitary region of New Zealand that occupies the southernmost part of the North Island. The region covers an area of 8,049 square kilometres (3,108 sq mi), and has a population of 550,500.
