Location of the Wilsons River mouth in New South Wales

Wilsons River, a perennial river and part of the Richmond River catchment, is situated in the Northern Rivers district of New South Wales, Australia.

The river rises on the eastern slopes of Jerusalem Mountain within the Nightcap National Park, and flows generally southeast, west southwest, and south, joined by five minor tributaries, before reaching its mouth at its confluence with the Richmond River, near Coraki; descending 359 metres (1,178 ft) over its 131 kilometres (81 mi) course.

The river passes through the major regional city of Lismore, where it is subject to seasonal flooding.

The traditional custodians of the land surrounding the Wilsons River are the Aboriginal people of the Bundjalung clan, who lived as hunter-gatherers.

Wilsons Creek was named after William Wilson, the first settler in Lismore, in the period 1844-5; and in 1976, the stream was renamed as Wilsons River.

Because of the extensive development of the catchment for agricultural and urban purposes the river system is adversely impacted by inputs of sediments, nutrients, gross pollutants and other contaminants. Efforts by Landcare groups and various government bodies such as the Northern Rivers Catchment Management Authority and Rous Water have been initiated to rehabilitate sections of the river.

New South Wales Fisheries have records that indicate the Eastern freshwater cod once was prevalent in the Wilsons River Catchment but no sightings have been recorded for many years and it is now thought to be locally extinct. In the lower portion of the Wilsons River the declared noxious species European Carp is common. Additionally, there are several species of noxious aquatic weed that occur such as Alligator Weed and Parrots Feather.
