The Darwin Mountains ( 79°51′S 156°15′E  /  79.850°S 156.250°E  / -79.850; 156.250  ( Darwin Mountains ) ) are a group of mountains between the Darwin Glacier and Hatherton Glacier in Antarctica. They were discovered by the British National Antarctic Expedition (1901–04) and named for Major Leonard Darwin , at that time Honorary Secretary of the Royal Geographical Society . They are south of the Cook Mountains and north of the Britannia Range
