The Snow River is a 28-mile (45 km) tributary of Kenai Lake in the U.S. state of Alaska. Beginning in the Chugach Mountains of the Kenai Peninsula, it flows southwest through Chugach National Forest to near Primrose at the southern inlet of the lake. The river mouth is about 12 miles (19 km) northeast of Seward. Along its final reaches, the river intersects the Iditarod Trail and passes under the Seward Highway.
