Cook Ice Shelf is an ice shelf about wide, occupying a deep recession of the coastline between Cape Freshfield and Cape Hudson, to the east of Deakin Bay. This indentation was called Cook Bay by the Australasian Antarctic Expedition, 1911–14, under Douglas Mawson, who named it for Joseph Cook, Prime Minister of Australia in 1914. The generic term has been amended, as the bay is permanently filled by an ice shelf.
