The Dog Salmon River is a 70-mile (110 km) tributary of the Ugashik River in the U.S. state of Alaska. Beginning on the flanks of Mount Kialagvik, it flows northwest through the Alaska Peninsula National Wildlife Refuge to meet the larger river 4 miles (6 km) southwest of Ugashik, at the head of Ugashik Bay, an arm of Bristol Bay. It descends to the upper reaches of the bay from an elevation of 981 feet (299 m) in a valley of the Aleutian Range between Mount Chiginagak and Mount Kialagvik. Among its feeder streams are Figure Eight, Goblet, and Wandering creeks.
