Coldfoot is a census-designated place in Yukon-Koyukuk Census Area in the U.S. state of Alaska. The population was 34 at the 2020 census. It is said that the name was derived from travelers getting "cold feet" about making the 240-some-mile journey north to Deadhorse. Coldfoot primarily serves as a truck stop on the Dalton Highway from Fairbanks to Prudhoe Bay. North of Coldfoot, there are no services for 240 miles, until Deadhorse.
