Wanganui is an urban area and district on the west coast of the North Island of New Zealand. It is part of the Manawatu-Wanganui region.
Like several New Zealand centres, it was officially designated a city until administrative reorganisation in 1989, and is now run by a District Council. Despite this, it is still regarded as a city by most New Zealanders.
Wanganui is located on the South Taranaki Bight, close to the mouth of the Whanganui River. It is 200 kilometres north of Wellington and 75 kilometres northwest of Palmerston North, at the junction of State Highways 3 and 4. Most of the town lies on the river's northwestern bank, although some suburbs are located on the opposite side of the river.
