The Noatak River () (also Noatok, Noatuk, Nunatok, or Notoark) is a river in the northwestern part of the U.S. state of Alaska. Leaving Gates of the Arctic National Park the river enters the Noatak National Preserve which exactly delineates the river's watershed. The entire watershed of the Noatak River lies within these two protected areas, from the headwaters to where it leaves the Noatak National Preserve, which is a point approximately 20 river miles upstream of Noatak village and 90 river miles upstream of the river's delta in Kotzebue Sound. Even on this last part of the river most of the watershed lies within either Noatak National Preserve or Cape Krusenstern National Monument, with only the immediate river valley outside of these protected areas. The Noatak basin is the largest undisturbed watershed in the United States. The Noatak National Preserve alone encompasses .

The Noatak is fed by a relatively large watershed: as for some other large braided Arctic rivercourses, rare severe rain events can result in temporary rapid inundation, to a depth of several feet, of normally dry river bars. There are a few small remnant glaciers in the Schwatka Mountains, their contribution to the water budget of the Noatak is negligible.

Name origin

Named Inland River by surgeon John Simpson of the Royal Navy on a map he prepared in 1853, his wording appears to be a general translation of the Inuit name Nunulak, according to the United States Geological Survey.
