The Nulato Hills are a mountain range in western Alaska between the Yukon River and Norton Sound.

In the north, they merge into the lowlands of the Selawik River, in the south they extend into the Yukon-Kuskokwim Delta.

At the Seward Peninsula level, the continental divide runs through the Nulato Hills.

The highest mountain in the Nulato Hills is Peak 4030 at 4,030 ft (1,228 m).
