Cape Corwin is the easternmost point of Nunivak Island in the Bering Sea in the U.S. state of Alaska. In the Cup'ig language it is known as Cing'ig ("point", as in point of land). According to Donald Orth (1967, Dictionary of Alaska Place Names) the name marks the southwest entrance point to Etolin Strait. According to local usage the feature is misnamed on official United States Geological Survey maps. Since the name was reported to USGS by the USCGS in "about 1908" (the Board of Geographic Names decision was in 1906, and Baker reports USCGS began using it in 1899) it may have subsequently migrated to the next northernmost point of land, Cing'ig. The 1911 USCGS chart does not accurately represent the shape of the coast here; the point and the cape are not separately identifiable.
