The Walker Mountains (72°07′S 99°0′W / 72.117°S 99.000°W / -72.117; -99.000 (Walker Mountains)) are a range of peaks and nunataks which are fairly well separated but trend east–west to form the axis, or spine, of Thurston Island in Antarctica.

The Walker Mountains form the spine of Thurston Island, running from west to east along the length of the island. Features, from west to east, include Landfall Peak, Mount Lopez, Mount Caldwell, Henderson Knob, Mount Kazukaitis, Mount Simpson, Mount Noxon, Mount Leech, Mount Hubbard, Smith Peak, Mount Borgeson, Guy Peaks, Mount Hawthorne, Mount Bramhall, Zuhn Bluff and Parker Peak.

The Walker Mountains were discovered by Rear Admiral Richard E. Byrd and members of the United States Antarctic Service (USAS) in a flight from the ship Bear on February 27, 1940. They were named by the United States Advisory Committee on Antarctic Names (US-SCAN) for Lt. William M. Walker, captain of the United States Exploring Expedition ship Flying Fish which reached a point 100 mi N of Thurston Island on March 23, 1839.
