Mountain group in Marie Byrd Land, Antarctica

The Mackay Mountains are a prominent group of peaks south of the Allegheny Mountains in the Ford Ranges of Marie Byrd Land, Antarctica.

The Mackay Mountains are south of the upper Boyd Glacier and east of the Hammond Glacier. They are southeast of the Sarnoff Mountains, south of the Allegheny Mountains and southwest of the Clark Mountains. The isolated Lewisohn Nunatak is to the southeast. Features, from west to east, include Vivian Nunatak, Mount Monson and Mount Palombo.

The Mackay Mountains and Lewisohn Nunatak contain the Lewisohn Member, a volcano dominated unit of the Swanson Formation, which is a quartzose metaflysch sequence at least thick that was probably deposited on a submarine fan. In Mackay Mountains the isochron age for the metamorphism of the Swanson Formation is 444 ± 4Ma.

The Mackay Mountains were discovered by the Byrd Antarctic Expedition (ByrdAE) in 1934. They were named for Clarence Mackay of the Postal Telegraph and Mackay Radio Companies, a benefactor of the expedition.
