Ranrapalca (possibly from Quechua ranra stony, pallqa bifurcation, division into two parts) is a mountain in the Cordillera Blanca range in the Andes of Peru. It has an elevation of 6,162 m (20,217 ft). It is located in the region of Ancash, east of Ocshapalca. Its territory is within Huascarán National Park, province of Huaraz, within the territory of the local communes Independencia and Tarica.

The northeast ridge (normal route) is of intermediate difficulty (rated D range according to the International French Adjectival System). It consists in climbing a steep, rocky ridge from the Ranrapallqa-Ischinca col to the summit snowfields and 6,000 m and then traverse south of the knife edge summit. An easier variant of the normal route consists in avoiding the northeast ridge. From the Ranrapallqa-Ischinca col the summit snowfields can be reached climbing the easy snow slopes on the left of the ridge but this route, albeit slightly easier is more exposed to seracs and loose rocks. Many other routes exist, some of them quite difficult (such as the east ridge and south face, both rated TD+).

Ranrapalca was first climbed by Hans Schweizer, Karl Schmid, Siegfried Rohrer and Walter Brecht (Germany) 25 June 1939.

Other data from available digital elevation models: SRTM 6132 metres, ASTER 6108 metres and TanDEM-X 6067 metres. The height of the nearest key col is 3253 meters, leading to a topographic prominence of 2909 meters. Ranrapalca is considered a Mountain Sub-System according to the Dominance System and its dominance is 47.21%. Its parent peak is Chinchey and the Topographic isolation is 10 kilometers.
