Russky Island (остров Русский), also spelt Russkyy and Russkiy, meaning "Russian Island", is an island in the Kara Sea. It is located in the Litke Islands subgroup of the Nordenskiöld Archipelago. With and area of 309 km², Russky is the biggest island in the whole archipelago. At a latitude of 77° 03' N, it is also the northernmost island of the group.
In 1939 the workers of the Russky Island station made the measuring of the ice layer and the height of embacles on the perpendicular to the bank section as a present to the 18th Congress of the Communist Party of the Soviet Union.
On the 25th August 1942, during Operation Wunderland, Kriegsmarine cruiser Admiral Scheer fell upon Russian Icebreaker Sibiryakov (under the command of Captain Kacharev) right off the northwest coast of Russky Island while prowling the waters off the northern end of the Nordenskiöld Archipelago. After opposing heroic resistance, the Sibiryakov was sunk in an unequal battle. Then Admiral Scheer headed southwest in order to attack the Soviet military installations at Dikson.
Scientific research on Russky Island, like the monitoring of animal species on the island (lemming, purple sandpiper, turnstone, sanderling, and little stint) was conducted after the break up of the Soviet Union, but the Arctic station was closed in 1999.
