The Arkticheskiy Institut Rocks () are a group of rocks lying north of the Nordwestliche Insel Mountains at the northwest extremity of the Wohlthat Mountains, Queen Maud Land. They were discovered and photographed by the Third German Antarctic Expedition, 1938–39, and mapped by the Soviet Antarctic Expedition, 1960–61, being named for that nation's Arctic Institute.
