Auckland City was a local authority district governed by Auckland City Council. It was the part of Auckland urban area covering the isthmus and most of the islands of the Hauraki Gulf. The core of Auckland City was the Auckland CBD, a major financial and commercial centre, surrounded by many suburbs.

It lay within the wider Auckland Region, which was governed by Auckland Regional Council. Auckland City was disestablished as a local government district on 1 November 2010, when Auckland City Council was amalgamated with other councils of the Auckland Region into the new Auckland Council.

Auckland City was the most populous district in the country, with a population of 450,000 at 30 June 2010. In 2009, Auckland was rated the fourth-best place to live in the world, in human resources consultancy Mercer's annual survey.

The mainland part of Auckland City occupied the Auckland isthmus, also known as the Tāmaki isthmus. The Waitemata Harbour, which opens to the Hauraki Gulf, separated North Shore City from the isthmus. The Manukau Harbour, which opens to the Tasman Sea, separated Manukau City from the isthmus. The distance between the two harbours is particularly narrow at each end of the isthmus. At the western end, the Whau River, an estuarial arm of the Waitemata Harbour, comes within two kilometres of the waters of the Manukau Harbour on the west coast and marks the beginning of the Northland Peninsula. A few kilometres to the southeast at Otahuhu, the Tamaki River, an arm of the Hauraki Gulf on the east coast, comes just 1200 metres from the Manukau's waters. Being part of the Auckland volcanic field, much of the isthmus is mantled with volcanic rocks and soils, and several prominent scoria cones dot the isthmus.
