The river has its source just south of the boundary between the Atlantic and Saint Lawrence river watersheds. It flows south-east to the Labrador–Quebec border from where it flows southward. In Quebec, the river forms the boundary between the Minganie and Golfe-du-Saint-Laurent Regional County Municipalities before draining into the Gulf of Saint Lawrence, about 370 kilometers (230 mi) east from Sept-Îles. The name is of Innu origin, who call it Nutahquaniu Hipu, meaning "river where black bear is hunted".
The Natashquan River is entirely within the Grenville geologic province of the Canadian Shield, characterized by a hilly plateau, ranging in altitude from 140 meters (460 ft) to 620 meters (2,030 ft), and consisting of felsic and metamorphic rock (such as gneiss, migmatite and granite), clastic rock (quartzite) and schists in the lower portion, with a few intrusions of mafic rock (diorite and gabbro) in the central part. The river largely runs through narrow valleys, and is fed by about 30 tributaries, of which the most significant are in downstream order: the Lejamtel, Mercereau, Mahkunipiu, Mistanipisipou, East Natashquan, Pehatnaniskau, Doré, West Natashquan, and Akaku Rivers.
The last 18 kilometers (11 mi) of the river forms a large sandy estuary, separated from the gulf by Natashquan Point and Cape Tiennot. Sainte-Hélène Island (île Sainte-Hélène) is located at the very mouth of the river.
In 1534, Jacques Cartier sailed by the area and named Cape Thiennot after a ship captain that had settled at that location. The river was mapped in 1684 by Louis Jolliet who called it "Noutascoüan". Jacques-Nicolas Bellin identified it as "Grand R. Natachquoin" on his map of 1744, while the 1776 map by Carver showed "Great Natashkwen".
From as early as 1710, a trading post was established on the left (south) bank of the Natashquan River and later on the opposite bank (at the river's mouth at present-day Natashquan FN Reserve) to conduct fur trade with the indigenous Innu people. The post was acquired by the Hudson's Bay Company in the middle of the 19th century, but abandoned circa 1914 due to lack of profitability.
An area of 4,089 square kilometres (1,579 sq mi) is being considered for protection in a biodiversity reserve. The reserve, mostly within the Petit-Mécatina unorganized territory, will extend 190 kilometres (120 mi) along the Natashquan River southward from the Labrador–Quebec border and also include 105 kilometres (65 mi) of the East Natashquan River. Furthermore, some 16,000 square kilometres (6,200 sq mi) is under study to be included in a new park, the Natashquan-Aguanus-Kenamu National Park.
The landscape of proposed reserve is deemed to have great beauty, exceptional value, recognized heritage interest, and considerable cultural interest. Therefore, the reserve is meant to protect favourable Atlantic salmon habitats, biodiversity of aquatic and riparian habitats, and old-growth forests. It will also manage sustainable harvesting of fur-bearing animals and develop tourism opportunities, while prohibiting mining, forestry, and hydro-electric development.
