Chukotka (/tʃʊˈkɒtkə/ chuu-KOT-kə; Russian: Чукотка [tɕʊˈkotkə]), officially the Chukotka Autonomous Okrug, is the easternmost federal subject of Russia. It is an autonomous okrug situated in the Russian Far East. It shares a border with the Sakha Republic to the west, Magadan Oblast to the south-west, and Kamchatka Krai to the south, as well as a maritime border on the Bering Strait with the U.S. state of Alaska to the east. Anadyr is the largest town and the capital, and the easternmost settlement to have town status in Russia. It is the closest point from Russia to the United States, measuring at 88.51 kilometres or 55 miles.
Chukotka is primarily populated by ethnic Russians, Chukchi, and other indigenous peoples. It is the only autonomous okrug in Russia that is not included in, or subordinate to, another federal subject, having separated from Magadan Oblast in 1992. It is home to Lake Elgygytgyn, an impact crater lake, and Anyuyskiy, an extinct volcano. The village of Uelen is the easternmost settlement in Russia and the closest substantial settlement to the United States (Alaska).
