Chefornak (Central Yupik: Cevvʼarneq) is a city in Bethel Census Area, Alaska, United States.

Chefornak is located at 60°9′33″N 164°16′10″W / 60.15917°N 164.26944°W / 60.15917; -164.26944 (60.159070, -164.269437)[6] on the south bank of the Kinia River, 16 miles (26 km) upriver from its mouth in Etolin Strait, an arm of the Bering Sea.

The Kinia River (Urrsukvaaq) and its many tributaries are important to the people of the village, because of water travel to hunting and fishing areas, as well as because of difficulties presented by flooding and erosion.

Many of the villagers live a subsistence lifestyle, which means that they continue to carry out the hunter-gatherer activities that their ancestors developed adapted to the local ecosystem.

Important staples include fish such as halibut, salmon, and herring, which are dried and eaten like jerky.

The Alaska blackfish is an important part of the local diet, and can be caught year round in the river.

[11] People access the village of Chefornak primarily by small aircraft but can also reach it via snowmobile in the winter.

Goods and mail are brought into the village by plane and, during the summer months, up the Kinia River by barge.
