The Kolyma (Russian: Колыма, IPA: [kəlɨˈma]; Yakut: Халыма, romanized: Xalıma) is a river in northeastern Siberia, whose basin covers parts of the Sakha Republic, Chukotka Autonomous Okrug, and Magadan Oblast of Russia.

The Kolyma is frozen to depths of several metres for about 250 days each year, becoming free of ice only in early June, until October.
