The John River is a right tributary of the Koyukuk River in the Interior of Alaska .

It has its source at Anaktuvuk Pass in the Brooks range , flows south and flows into the Koyukuk River near the Arctic Circle .

The John River flows in the upper reaches of the Brooks range through wide valleys formed by glaciers. In the lowlands on the lower reaches, steep banks limit the river bed for long stretches.

The Arctic caribou herd uses the river's valley on their migrations. The tragacanth type William's Milk Vetch occurs only in this region.

Archaeological finds show that the Anaktuvuk Pass was used a long time ago by the indigenous people of Alaska .

The 84 km long section of the John River in Gates-of-the-Arctic National Park was designated as a National Wild and Scenic River under the administration of the National Park Service in 1980 by the Alaska National Interest Lands Conservation Act .
