Fang Ridge (77°29′S 167°11′E) is a conspicuous ridge on the northeast slope of Mount Erebus, on Ross Island. It is a much denuded portion of the original caldera rim left by a catastrophic eruption. It was so named, probably for its curved shape, by Frank Debenham of the British Antarctic Expedition, 1910–13, who made a plane table survey in 1912.
