The Unalakleet River (Iñupiaq: Uŋalaqłiit Kurgat) in the U.S. state of Alaska flows southwest 90 miles (145 km) from the Kaltag Mountains to near the town of Unalakleet, on Norton Sound of the Bering Sea.

[4] Other forms of recreation along the river include boating and camping in summer and snowmobiling, dog mushing, ice fishing, hunting, and trapping in winter.

[6] The route, including what is called the Kaltag Portage, was the shortest connection between the Yukon and Norton Sound.

Shortly thereafter, prospectors seeking gold on the nearby Seward Peninsula traveled over the Kaltag Portage and downriver to the coast.

Subsequent changes included a telegraph line and associated cabins along the river and establishment of a mail route.
