Project 22220, also known through the Russian type size series designation LK-60Ya, is a series of Russian nuclear-powered icebreakers. The lead ship of the class, Arktika, was delivered in 2020 and surpassed the preceding Soviet-built series of nuclear-powered icebreakers as the largest and most powerful icebreaker in the world.

As of November 2025, four Project 22220 icebreakers (Arktika, Sibir, Ural and Yakutiya) are in service, the fifth (Chukotka) has been launched, and the sixth (Leningrad) and seventh (Stalingrad) have been laid down at Baltic Shipyard in Saint Petersburg.
