Chevak (Cevʼaq , which means "cut-through channel" in Chevak Cup’ik) is a city in Kusilvak Census Area, Alaska, United States. At the 2020 census the population was 951, up from 938 in 2010.

There is a tri-language system in Chevak; English, Cup’ik, and a mixture of the two languages. The people in Chevak speak a dialect of Central Yup'ik, Cup'ik (pr. Chew-pick), and identify themselves as Cup'ik people rather than Yup'ik. This unique identity has allowed them to form a single-site school district, the Kashunamiut School District, rather than joining a neighboring Yup'ik school district. The Cup'ik dialect is distinguished from Yup'ik by the change of "y" sounds into "ch" sounds, represented by the letter "c", and by some words that are completely different from Yup'ik words.

Chevak is located at 61°31′40″N 165°34′43″W / 61.52778°N 165.57861°W / 61.52778; -165.57861 (61.527673, -165.578702) in the Yukon-Kuskokwim Delta region of southwest Alaska, approximately 6 miles from the Bering Sea coastline, 18 miles east of Hooper Bay and 26 miles south of Scammon Bay. Transportation into, and out of, Chevak is by air or water, or regional ice roads in the winter. As with many communities in Alaska, Chevak is not connected to the national road network.

Chevak is powered by four 30-meter-tall wind turbines. The wind generated in Chevak is classified as "Class 6 – Outstanding", and is owned and operated by AVEC (Alaska Villages Electric Cooperative).

In addition, electrical power is supplied by four diesel generators capable of supplying up to a combined 1828 kilowatts of electricity year-round, with the tank farm storing up to 302,000 gallons of diesel fuel. This, in addition to the 400 kilowatts generated by the wind turbines, gives Chevak’s electrical grid a total capacity of 2228 kilowatts.

As of 2022, all buildings in Chevak have running water and piped sewage, supported by a central water treatment facility built in 1984, and a central wastewater treatment plant built in 2001. An outage, due to the old school fire in 2021, affected service to the eastern half of Chevak, with many residents forced to resort back to honey buckets as toilets.

Internet access is provided by GCI via their TERRA microwave network. There is 3G cellular coverage as well as broadband available for residents and businesses.

In 2021, the old school, shut down for renovations and removal of toxins such as asbestos, was destroyed in a fire. The old school was planned to be turned into a community center, before its destruction. Two individuals went missing at the time of the fire, which resulted in the Alaska State Troopers launching an investigation. The cause of the fire is still unknown. The Alaska Department of Environmental Conservation is providing 2.5 million dollars in funds towards the cleanup effort and removal of debris from the destroyed school.
