The Selway River is a large tributary of the Middle Fork of the Clearwater River in the U.S. state of Idaho. It flows within the Selway-Bitterroot Wilderness, the Bitterroot National Forest, and the Nez Perce National Forest of North Central Idaho. The entire length of the Selway was included by the United States Congress in 1968 as part of the National Wild and Scenic Rivers Act.

The main stem of the Selway is 100 miles (160 km) in length from the headwaters in the Bitterroots to the confluence with the Lochsa near Lowell to form the Middle Fork of the Clearwater. The Selway River drains a 2,013-square-mile (5,210 km2) basin in Idaho County.
