Kolyuchin Bay

Kolyuchin Bay is a large bay in the Chukchi Sea on the northern shore of the Chukotka Peninsula, Russia.

Administratively this bay belongs to the Chukotka Autonomous Okrug of the Russian Federation.


To the west is Cape Vankarem and to the east Neskynpil'gyn Lagoon and Cape Serdtse-Kamen. The length of the bay is 100 km. Its mouth is only 2.8 km because of the Serykh Gusey Islands and the Belyaka Spit, separate it from the Arctic Ocean. The width increases to 37 km as it goes southwards and inland.

The depth of Kolyuchinskaya Bay is 7 to 14 m. The bay is covered with ice most of the year.

This bay has an inlet in its southern end known as the Kuetkuyyim Inlet. The Ioniveyem and the Ulyuveyem River flow into it from the south.


In 1793, the bay was named Count Bezborodko Bay in honor of Russian statesman Alexander Bezborodko. The locals could not get accustomed to this name and the bay was later renamed Kolyuchinskaya after nearby Kolyuchin Island.
