Mount Harcourt, also known as Mount Vernon Harcourt, is a stratovolcano (1,570 m) making up part of the Hallett Peninsula, Victoria Land, Antarctica, extending into the Ross Sea about 375 mi (604 km) south of Mount Erebus, along with three overlapping shield volcanoes. It was discovered in January 1841 by Sir James Clark Ross and named by him for the Reverend William Vernon Harcourt, one of the founders of the British Association.

Two dates have been obtained from the volcano's rock, roughly 5.5 and 6.6 million years in age. These samples are alkalic in composition.[1] The volcano is known to be a site of Boscoia sudpolaris.[2]
