Ōrākei is a suburb of Auckland city, in the North Island of New Zealand. It is located on a peninsula five kilometres to the east of the city centre, on the shore of the Waitematā Harbour, which lies to the north, and Hobson Bay and Ōrākei Basin, two arms of the Waitematā, which lie to the west and south. To the east is the suburb of Mission Bay. Takaparawhau / Bastion Point is a coastal piece of land in Ōrākei. Between Takaparawhau and Paritai Drive is Ōkahu Bay and Reserve.

Waitematā Harbour is the main access by sea to Auckland, New Zealand. For this reason it is often referred to as Auckland Harbour, despite the fact that it is one of two harbours adjoining the city. The harbour forms the northern and eastern coasts of the Auckland isthmus and is crossed by the Auckland Harbour Bridge. It is matched on the southern side of the city by the shallower waters of the Manukau Harbour.
