  Berkley Island (66°13′S 110°39′E﻿ / ﻿66.217°S 110.650°E﻿ / -66.217; 110.650) is an island, 1 km long, which marks the north-eastern end of the Swain Islands. It was first mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was included in a survey of the Swain Islands in 1957 by Wilkes Station personnel under Carl R. Eklund. It was named by Eklund for Richard J. Berkley, a geomagnetician with the US-IGY wintering party of 1957 at Wilkes Station.
  
  ## Important Bird Area
  
  The island, along with neighbouring Cameron Island, the intervening sea and smaller islets, has been identified as a 97 ha Important Bird Area by BirdLife International because it supports some 14,000 pairs of breeding Adélie penguins (as estimated from January 2011 satellite imagery). It lies about 9 km east of Australia's Casey Station.
