The Kolomeytseva Islands (Russian: острова́ Коломе́йцева, ostrova Kolomeytseva) is a group of two small islands, part of the Nordenskjold Archipelago in the Kara Sea coastal region, off the coast of Siberia. These two islands are about 40 kilometers (25 mi) east of Russky Island, the largest island of the Nordenskjold Archipelago, and less than 100 kilometers (62 mi) west of the Taymyr Peninsula.
The sea surrounding the little Kolomeytseva Islands is covered with fast ice in the winter and the climate is severe. The surrounding sea is obstructed by pack ice even in the summer.
These islands belong to the Krasnoyarsk Krai administrative division of Russia and is part of the Great Arctic State Nature Reserve, the largest nature reserve of Russia.
In 1900, the islands of the Nordenskiöld Archipelago were explored by Russian geologist Baron Eduard Von Toll during the Polar Expedition on behalf of the Imperial Russian Academy of Sciences aboard ship Zarya. The islands were named after Captain Nikolai Kolomeitsev, first commander of the ship.
