The name is translated from Russian Четырехсопочные Острова (Ostrova Chetyre Soposhnye) meaning "Islands of Four Volcanoes" (Sarichev, 1826, map 3). The early Russian explorers named the islands by this term because of four prominent volcanoes, each located on a separate island. The Aleut name Unigun (Uniiĝun{{Cite book| first=K. | last=Bergsland | author-link=Knut Bergsland | year=1994 | title=Aleut Dictionary |publisher=Alaska Native Language Center |location=Fairbanks }} in the modern Aleut orthography) was reported in 1940 by Father Veniaminov. There appears to be confusion regarding the names of these islands, possibly because only four of the five are on most early maps and charts. The present names were gathered in 1894 by a field party from {{USS|Concord|PG-3|6}} and published in 1895 by the U.S. Navy Hydrography Office (Chart 8).{{cite gnis|id=1403972|name=Islands of Four Mountains|access-date=2006-06-07}}
