Mount Brown (-68.566°N 86.1008°W) is an elongated rock peak protruding slightly above the continental ice, situated east of the Vestfold Hills and south-southwest of Cape Penck in Antarctica. It was delineated from aerial photos taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names for Lieutenant (j.g.) Eduardo P. Brown, U.S. Navy, photographic officer for the Western Group of the expedition.
