The Kamchatka brown bear (Ursus arctos beringianus), also known as the Far Eastern brown bear, is a subspecies of brown bear native to the Anadyrsky District, the Kamchatka Peninsula, Karaginskiy Island, the Kuril Islands, the coastal strip west of the Sea of Okhotsk southward to the Stanovoy Range and the Shantar Islands. Outside the former Soviet Union, the subspecies occurs in Saint Lawrence Island in the Bering sea. It is closely related to one clade of brown bears in Alaska and northwest North America, and is thought to be the ancestor of the Kodiak bear.
