Tutukaka (Māori: Tūtūkākā) is a locality on the east coast of Northland, New Zealand, in an area commonly referred to as the Tutukaka Coast which includes Ngunguru and Matapouri. The city of Whangārei is to the southwest. The residential areas of Tutukaka fringe the hills surrounding Tutukaka Harbour, which has a history as a local fishing port and hosts Tutukaka's marina. The Māori name comes from the term tūtū kākā, which means a parrot (kākā) snaring tree (tūtū).

As the closest marina to the Poor Knights Islands, Tutukaka is the base for boat tours for diving and snorkelling in the waters around these islands, a protected marine reserve. At the peak of the busy summer months, Tutukaka's population swells from around 600 permanent residents to over 2,400. A walking track leads from Tutukaka to a small lighthouse at Tutukaka Head (South Gable).

Statistics New Zealand describes Tutukaka as a rural settlement. The settlement covers 6.98 km (2.69 sq mi) and had an estimated population of 830 as of June 2023, with a population density of 119 people per km. The settlement is part of the larger Matapouri-Tutukaka statistical area.
