The John River (Iñupiaq: Atchiiniq) is a  tributary of the Koyukuk River in the northern part of the U.S. state of Alaska. It was named after John Bremner, a prospector and explorer who was one of the first non-native persons to go there. It flows south from Anaktuvuk Pass in Alaska's Brooks Range, into the larger river at a point near Bettles, slightly north  of the Arctic Circle. In 1980, the  segment of the John River within the Gates of the Arctic National Park and Preserve were designated "wild" and added to the National Wild and Scenic Rivers System. The designation means that the segment is unpolluted, free-flowing, and generally inaccessible except by trail. The John River Valley is an important migration route for Arctic caribou. History
In 1901, the Schrader-Peters expedition explored the John River, the Anaktuvuk River, and continued onward to Point Barrow. In 1931, Robert "Bob" Marshall explored the John River up to the Arctic Divide, and described seeing a "quadruple rainbow". Boating
It is possible to run the John River in canoes, kayaks, and small rafts, though conditions vary from place to place. The upper  are rated Class III (difficult) on the International Scale of River Difficulty and "should be attempted only by experienced paddlers with solid wilderness skills." Below this, the river is rated Class II (medium) for the next , then Class I on the lower reaches all the way to the mouth. Dangers on the upper river include sustained whitewater, swift currents, a difficult  portage, and the possibility of water too shallow to run. See also
