National Preserve along the Noatak River in northwestern Alaska

Noatak National Preserve is a United States National Preserve in northwestern Alaska that was established to protect the Noatak River Basin. The Noatak River system, located just north of the Arctic Circle, is thought to be the last remaining complete river system in the United States that has not been altered by human activities. The roadless basin was proclaimed a United States National Monument in 1978 and a National Preserve in 1980 through the passage of the Alaska National Interest Lands Conservation Act (ANILCA). Noatak National Preserve borders Kobuk Valley National Park on the south and Gates of the Arctic National Park on the east. Unlike the national parks that it borders, sport hunting is allowed in Noatak National Preserve. All of the preserve, except for about east of the village of Noatak, has been designated the Noatak Wilderness. The wilderness is the fourth largest in the United States, following the Wrangell Saint Elias Wilderness, the Mollie Beattie Wilderness, and the Gates of the Arctic Wilderness.

The preserve includes the transition zone from boreal forest to tundra near the southern edge of the preserve. The Noatak Basin is a transition zone for plants and animals between Arctic and subarctic environments. The lower portion of the Noatak valley has areas of boreal forest, but most vegetation is low growing tundra species. Alpine tundra occurs at high elevation, and moist tundra, the most common condition, supports cottongrass, willows, Labrador tea, mountain alder, dwarf birch and other tundra species at lower elevations. Boggy areas support cranberry, bog rosemary and salmonberry. The central feature of the preserve is the Noatak River, and is a breeding ground for a variety of commercially important fish. The most widespread salmon species is chum, and pink, chinook and sockeye salmon are found as well. Several kinds of trout are found in deep lakes, with Arctic char and Arctic grayling the most common salmonids in the preserve. Burbot are also found, as are nelma or sheefish, an important species for subsistence fisheries. Float trips on the Noatak River are a popular way to see the preserve. However, most trips on the Noatak River take place high on the river in Gates of the Arctic National Park, typically from Twelve Mile Creek to Lake Matcherak. Longer trips can continue through the preserve, although the lower river's braided stream presents difficulties beyond Noatak village. There are a few rapids on the river of Class II+, although most of the river is Class I or Class II. Float trip season runs from June or July, when the river thaws, to September. Biting insects are most prevalent in June and July.

The The distance from the headwaters in Gates of the Arctic National Park to Noatak, Alaska is about 354 mile (570 km). Offices and visitor services for Cape Krusenstern National Monument and Kobuk Valley National Park are in the same facility. The units are managed together as the Western Arctic National Parklands, with a single Park Service superintendent in charge. A portion of the Noatak valley was designated a World Biosphere Reserve in 1976, prior to the preserve's establishment, and was withdrawn from the program in June 2017. 330 mile (531 km) of the Noatak, from its source in Gates of the Arctic National Park to the Kelly River in the Noatak National Preserve, were designated a National Wild and Scenic River as part of the ANILCA legislation.
