Rivière-aux-Outardes (French pronunciation: [ʁivjɛʁ oz‿utaʁd]) is an unorganized territory in the Côte-Nord region of Quebec, Canada.

The eponymous Outardes River is nearly 400 kilometres (250 mi) long, and flows through the territory in a north–south direction before draining into Outardes Bay at Ragueneau.

Both these rivers are developed with large-scale hydroelectric installations, part of the Manic-Outardes Project.

Quebec Route 389, running for a large part between the Outardes and Manicouagan Rivers, provides access to the territory and the hydroelectric installations along these rivers.

It is an isolated highway with few roadside services that are great distances apart.
