Mudyug (Russian: Мудьюг) is a Russian icebreaker and the lead ship of a series of three subarctic icebreakers built at Wärtsilä Helsinki shipyard in Finland in 1982–1983. The vessel's non-rebuilt sister ships are Magadan and Dikson.

Mudyug was rebuilt with a new Thyssen-Waas icebreaking bow at Nordseewerke in 1986.
