is a federally designated wild and scenic river partially contained within the boundaries of Gates of the Arctic National Park, Alaska.

The Alatna River stems from the central Brooks Range flowing through the Endicott Mountains, passing Circle Lake, the Arrigetch Peaks and Takahula Lake before entering the Helpmejack Hills.

The river then mellows out near Takahula and Circle Lake becoming deeper and more meandering while the scenery turns from mountain peaks into hilly boreal forest.

The river is very popular for float trips due to its calm flow and wonderful scenery.
