The Fortymile River is a 60-mile (97 km) tributary of the Yukon River in the U.S. state of Alaska and the Canadian territory of Yukon. Beginning at the confluence of its north and south forks in the Southeast Fairbanks Census Area, the Fortymile flows generally northeast into Canada to meet the larger river 32 miles (51 km) southeast of Eagle, Alaska.
