The Dunay Islands are a small group of Arctic islands in the Sakha Republic (Yakutia), Russian Federation, located in the Laptev Sea. They form part of the high-latitude island groups off northern Siberia.

The islands are primarily of interest for Arctic geology, tundra ecology and seabird colonies rather than tourism infrastructure. There are no permanent settlements and the landscape is tundra and low-lying coastal terrain.

Like many small Arctic islands in the region, the Dunay Islands have been used intermittently by indigenous and later Russian expeditions for hunting, scientific study and navigation; they contain natural features rather than significant built heritage.

The archipelago lies off northern Siberia in the Laptev Sea within the boundaries of the Sakha Republic, well north of the Arctic Circle.

  • Access and conditions: The islands are remote and lie within the Arctic climate zone; access is by specialised expedition or research vessels and is limited by sea ice for much of the year.
