Charrúa Ridge is an ice-free rocky ridge rising to 333 metres (1,093 ft) along the northeast coast of Johnsons Dock in Hurd Peninsula, Livingston Island, in the South Shetland Islands, Antarctica. It is narrow and precipitous, extending 700 metres (800 yd) in a west-northwest to east-southeast direction, with triple heights of elevation 322, 333 and 332 m respectively, and linked to Castillo Nunatak by Charrúa Gap. It surmounts Contell Glacier to the north, South Bay to the west, Johnsons Dock to the southwest and Johnsons Glacier to the south. It forms a prominent landmark in the area between the Spanish Antarctic base Juan Carlos I and the Bulgarian Antarctic base St. Kliment Ohridski.
