The Nushagak River (Iilgayaq in Central Alaskan Yup'ik) is a river in southwest Alaska, United States. It begins in the Alaska Range and flows southwest 450 km (280 mi) to Nushagak Bay, an inlet of Bristol Bay, east of Dillingham, Alaska.
The Nushagak River is downstream of the proposed Pebble Mine, whose tailings storage lake would sit at the headwaters of the Koktuli River, one of the Nushagak's tributaries. Villages on the Nushagak are among the major opponents of the proposal.
Five species of Pacific salmon (Chinook, coho, sockeye, chum, and pink) spawn in the river or its tributaries. Commercial, subsistence and sport fishing are important in the area. Most notable is the annual run of king (Chinook) salmon which occurs from mid-June to mid-July. Rainbow trout, northern pike, grayling, burbot, whitefish and Arctic char are also present in the Nushagak. It is estimated that over 50% of the world's production of wild salmon is harvested in the Nushagak River and the Bristol Bay area.
