Pucaranra, Mountain peak in Cordillera Blanca, Peru.

Pucaranra is a mountain in the Cordillera Blanca of the Andes in Peru, rising to about 6,147 metres, with other sources citing 6,156 metres. It stands southwest of Chinchey and beside Palcaraju, on the border of the Carhuaz and Huaraz provinces within Huascarán National Park. At its foot lies Palcacocha lake, in the Quebrada de Cojup.

Pucaranra was first climbed on 7 April 1948 by the Swiss mountaineers B. Lauterburg, Federico Marmillod, R. Schmid and F. Sigrist, who took the southwest spur of the south ridge. A Spanish-language account instead dates the Swiss expedition to 5 July 1948 and names the southeast ridge, led by Frédéric Marmillod with Ruedi Schmid, Bernhard Lauterberg and Fritz Sigrist. Later expeditions opened other routes to the summit.

The name Pucaranra comes from Quechua puka (red) and ranra (stony ground), meaning 'red stony ground'. The mountain stands above Palcacocha lagoon in the Cojup valley, and its Quechua name is still used by local people.

Visitors need a permit from Huascaran National Park and should allow time for acclimatization. A base camp at around 4,600 meters is necessary to adjust to the thin air.

Pucaranra's nearest key col drops to 3,253 metres, giving the mountain a topographic prominence of 2,903 metres and a dominance of 47.16 percent. Its parent peak is Chinchey, and the summit stands only 2.4 kilometres from it in straight-line isolation.
