Quimsachata[1][2] (possibly from Aymara and Quechua kimsa three,[3] Pukina chata mountain[4]) is an extinct volcano in the Andes of Peru.

It is located in the Cusco Region, Canchis Province at about 24 kilometres (15 mi) northwest of the town of Sicuani.

Volcanism in southern Peru occurs as part of two distinct volcanic systems, the stratovolcanoes of the Western Cordillera and the Altiplano volcanoes which are typically small systems with surface areas of less than 50 square kilometres (19 sq mi).

One of these lineaments is associated with the Cusco and Vilcanota faults which separate the Altiplano into a western and eastern portion.

Situated along the foot of the Eastern Cordillera, they are the northernmost young Peruvian volcanoes and lie far away from the principal volcanic arc.
