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 May 2025, four Project 22220 icebreakers (Arktika, Sibir, Ural and Yakutiya) are in service, a fifth (Chukotka) has been launched, a sixth (Leningrad) has been laid down at Baltic Shipyard in Saint Petersburg, and a seventh (Stalingrad) is under construction.
