Mount Usher is a distinctive mountain overlooking the south side of Keltie Glacier about 4 miles (6.4 km) southwest of the mouth of Brandau Glacier in Antarctica. Discovered and named by the British Antarctic Expedition (1907–09). Identification of this feature varied on subsequent maps. The present description follows the H.E. Saunders map of 1961 which has now been generally accepted.
