Chakrarahu (Quechua chakra little farm / field, land sown with seed, rahu snow, ice, mountain with snow, hispanicized spellings Chacraraju, Chakraraju, Chacrarrajo) is a mountain in the Cordillera Blanca in the Andes range of Peru. It has an elevation of 6,108 metres (20,039 ft). Chakrarahu is situated in the Ancash Region, Huaylas Province, Caraz District, and in the Yungay Province, Yungay District. It lies south and southeast of the mountain Pirámide. Parón Lake and the little lake named Chakra (Chacra) lie northwest of the mountain. The peak is accessible from the Pisco base camp at Cebollapampa.
Chakrarahu is considered the steepest and the most difficult-to-climb six-thousander in the Andes. A French expedition led by Lionel Terray first climbed the mountain on 5 August 1962 on what after as become the normal route (northeast ridge). Greg Mortimer was badly injured during a later attempt to climb the mountain.
