The Tubutulik River is a waterway in the U.S. state of Alaska. The 25-mile (40 km) long river is situated on the Seward Peninsula. It flows southeastwards to the Kwiniuk Inlet at the northwestern end of Norton Bay, 25 miles (40 km) southwest of Koyuk in the Bering Sea. Its Inuit name was reported as "Tubuktulik" in 1849 by Capt. Mikhail Dmitrievich Tebenkov of the Imperial Russian Navy. Exploration for placer gold occurred in the Council district area where the river valley is located, and in 1898, mining commenced.
