The Komandorski Islands or Commander Islands are a group of treeless islands east of the Kamchatka Peninsula in the Russian Far East, in the Bering Sea. The islands consist of Bering Island, Medny Island, and two small islets. Geologically, although separated from the rest of the chain by several hundred miles, the Commander Islands are the westernmost extension of the Aleutian Islands. The inhabitants, Russians and Aleuts, fish and hunt whales and other marine mammals. The largest village is Nikolskoye on Bering Island.
