Paramushir is a volcanic island in the northern portion of Kuril Islands chain in the Sea of Okhotsk in the northwest Pacific Ocean. It is separated from Shumshu by the very narrow Second Kuril Strait in the northeast 2.5 kilometres (1.6 mi), from Antsiferov by the Luzhin Strait (15 km) to the southwest, from Atlasov in the northwest by 20 kilometres (12 mi), and from Onnekotan in the south by the 40 km wide Fourth Kuril Strait. Its northern tip is 39 kilometres (24 mi) from Cape Lopatka at the southern tip of the Kamchatka Peninsula. Its name is derived from the Ainu language, from “broad island” or “populous island”. Severo-Kurilsk, the administrative center of the Severo-Kurilsky district, is the only permanently populated settlement on Paramushir island.
