Charrúa Ridge is an ice-free rocky ridge rising to along the northeast coast of Johnsons Dock in Hurd Peninsula, Livingston Island, in the South Shetland Islands, Antarctica. It is narrow and precipitous, extending 700m (2,300feet) 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.
The feature is named after the Charrúa, one of the ships of the Argentine Antarctic Expedition of 1947–48, and the name "Monte Charrúa" appears for this feature on a 1954 Argentine navy chart.
The summit of the ridge is located at -62.6564°N -60.3483°W which is southeast of Hespérides Point, 950m (3,120feet) south by west of Krum Rock, west of Castillo Nunatak and northwest of Napier Peak. (Detailed Spanish mapping in 1991, and Bulgarian in 1996, 2005 and 2009).
