Mount Estes () is a flattish mountain south of Mount Aurora in the southern part of Black Island in the Ross Archipelago. The mountain rises to and is similar to the flat Cape Beck massif that forms the south end of the island. It was named by the Advisory Committee on Antarctic Names (1999) after Steve A. Estes of the Geophysical Institute, University of Alaska, Fairbanks, who investigated the seismicity of nearby Mount Erebus, 1980–81 and 1981–82.
