Jirishanca or Hirishanca (in hispanicized spellings) is a mountain of the Waywash mountain range in west central Peru, part of the Andes. At 6,126 metres (20,098 ft) (other sources: 6,094 m (19,993 ft))[citation needed] it is the tenth highest in Peru and the third in the Waywash mountain range (after Yerupajá and Siula Grande).

First climbed in July 1956 by Toni Egger and Siegfried Jungmeir, the mountain is notoriously difficult and has been very few successful ascents. It is on average climbed less than once per year.

It is one of the hardest 6000m mountain of the Andes. The easier route to the summit is quoted TD but more difficult routes exist, many on them on vertical ice and with overhanging section of mixed terrain such as the Cassin route (70° ice and a pitch rated UIAA IV+).
