The Bush Mountains is a series of rugged elevations at the heads of the Ramsey and Kosco glaciers in Antarctica.

The Bush Mountains extend from Mount Weir in the west to Anderson Heights overlooking Shackleton Glacier in the east.

The Bush Mountains were named by the Advisory Committee on Antarctic Names (US-SCAN) on the recommendation of Rear Admiral Richard Evelyn Byrd, after James I. Bush, United States financier and patron of the Byrd AE, 1928–30.

A steep section of the polar plateau escarpment with almost all of the rock exposed facing northeast, standing just south of the base of Fulgham Ridge at the head of Ramsey Glacier.

A low, mainly ice-covered bluff that forms the southwest wall of Mincey Glacier in the Queen Maud Mountains.

The feature was so named by the Texas Tech-Shackleton Glacier Party, 1962-63, because water cascades over the bluff during warm periods.
