Tāmaki is a small suburb of East Auckland, 11 kilometres from the Auckland CBD, in the North Island of New Zealand. It is located by the banks of the estuarial Tāmaki River, which is a southern arm of the Hauraki Gulf. The suburb is between the suburbs of Point England to the north and Panmure to the south.

Tāmaki is under the local governance of Auckland Council. It is part of the much larger Tāmaki parliamentary electorate.

In the 1940s Tāmaki was chosen to be an area for large state housing development and continued to have state houses built for almost 20 years.

Tamaki covers 1.29 km (0.50 sq mi) and had an estimated population of 5,160 as of June 2024, with a population density of 3,969 people per km.

To the west of the suburb is Mount Wellington, a 137-metre volcanic peak which is part of the Auckland volcanic field, and which was formed by an eruption around 9,000 years ago.

By a quirk of geographical naming, the suburb of East Tāmaki is located several kilometres to the south of Tāmaki because it takes its name from the fact that it is on the eastern side of the Tamaki River, rather than from its relationship to Tāmaki.

The name Tāmaki was the Māori name for the Auckland isthmus, and was later applied to the eastern part of early Auckland (towards the Tamaki River), as in the name of the Tamaki Road Board.

The name Tāmaki is of contested origin. It is an ancient Polynesian word for battle; it can also mean full of people, i.e., heavily populated – an ironic possibility given that the Maori name of the heavily populated Auckland isthmus in Māori is Tāmaki-makau-rau. A third possible origin of the names is Tā-Maki, meaning successful attack by Maki, which was the name of a local tribal chief.
