Cape Corwin is the easternmost point of Nunivak Island in the Bering Sea in the U.S. state of Alaska.
According to local usage the feature is misnamed on official United States Geological Survey maps.
The 1911 USCGS chart does not accurately represent the shape of the coast here; the point and the cape are not separately identifiable.
[1] Cape Corwin may have been named for USRC Corwin[2] which patrolled the Bering Sea in the 1880s and 1890s and made systematic depth soundings around Nunivak Island in 1899[3] Capes Manning, Mohican, and Algonquin on Nunivak Island also correspond with ships (Revenue Service, Navy and Coast Guard, respectively) of the Bering Sea Squadron and the Bering Sea Patrol.
A 95-foot steel-hull U.S. Coast Guard patrol boat, built in 1958, operated as USCGC Cape Corwin from 1964 to 1990.
