Mount Worsley () is a mountain, 1,105 m, on the west side of Briggs Glacier in South Georgia. It was surveyed by the South Georgia Survey in the period 1951-57, and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Frank Arthur Worsley (1872-1943), skipper of the Endurance on 1914-16 Imperial Trans-Antarctic Expedition. Worsley accompanied Ernest Shackleton in the James Caird from Elephant Island to King Haakon Bay, South Georgia, and made the overland crossing with him to Stromness whaling station.
