Mount Irving is a mountain rising to ca. 1950 m that is the dominant elevation on Clarence Island, in the South Shetland Islands, Antarctica. (Some older sources used to give the elevation as 2300 m. ) The rounded, heavily glaciated mountain is situated in Urda Ridge occupying the southern part of the island. A prominent feature, the mountain doubtless was known to sealers in the area in the 1820s. It was named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Rear Admiral Sir Edmund George Irving, Royal Navy, Hydrographer of the Navy, 1960–66.
