The Newhalen River (Dena'ina: Nughiltnu) is a 22-mile (35 km) stream in the Lake and Peninsula Borough of the U.S. state of Alaska.

[1] Alaska Fishing describes the river as "the major pathway for a mind-boggling migration of sockeye salmon"[4] that ascend the stream in early summer.

The main game fish in addition to sockeye are rainbow trout.

However, waterfalls rated Class V (extremely difficult) on the International Scale of River Difficulty and other sections of whitewater rated Class IV (very difficult) mean that the river "is rarely run in its entirety".
