库克冰架是南极洲的冰架，位于乔治五世地，处于弗雷什菲尔德角和哈德森角之间，西面是迪金湾，宽90公里，以澳大利亚的总理命名，现时由南极条约体系管理。

Cook Ice Shelf is an ice shelf about 55 miles (90 km) 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.
