班克罗夫特湾是南极洲的海湾，位于葛拉汉地西岸，处于夏洛特湾和威尔米纳湾之间，以英国的测量员命名，现时由南极条约体系管理。

Bancroft Bay is a bay lying between Charlotte Bay and Wilhelmina Bay, along the west coast of Graham Land. The bay was first roughly indicated by the Belgian Antarctic Expedition under Gerlache, 1897–99. It was remapped by the Falkland Islands Dependencies Survey from air photos taken by the Falkland Islands and Dependencies Aerial Survey Expedition, 1955–57, and named by the UK Antarctic Place-Names Committee in 1960 for Anthony D. Bancroft, senior surveyor of the latter expedition.
