Urda Ridge (Bulgarian: Урдин хребет, ‘Urdin Hrebet’ \'ur-din 'hre-bet\) is the mostly ice-covered ridge occupying the interior of southern Clarence Island in the South Shetland Islands, Antarctica. It extends 8 km in north-northeast to south-southwest direction and 9 km in west-northwest to east-southeast direction, rising to 1950 m at the island’s summit Mount Irving,^[1] and is connected to Ravelin Ridge to the north by Soyka Saddle. The southeast slopes of the feature are drained by Dobrodan and Highton Glaciers, and its northwest slopes — by Skaplizo, Giridava and Bersame Glaciers. Urda is a Thracian place name from Southern Bulgaria.
