This article is about the Wanganui River in the South island of New Zealand. For the river of the southwestern North Island, formerly called the Wanganui, see Whanganui River

The Wanganui River is in the West Coast of the South Island of New Zealand. It flows northwest for 55 kilometres (34 mi) from its headwaters in the Southern Alps, entering the Tasman Sea near Lake Ianthe, 40 kilometres (25 mi) southwest of Hokitika.

After heavy rain in January 2013 the flooded river partially washed away the road bridge that carries State Highway 6, closing the only through road on the West Coast.[1]
