Mocho-Choshuenco (Pronounced: /ˈmɒtʃoʊ tʃɒsˈwɛnkoʊ/ MOTCH-oh choss-WEN-koh) is a glacier covered compound stratovolcano in the Andes of Los Ríos Region, Chile.

The southern and eastern slopes drain to Pillanleufú River which flows south along the Liquiñe-Ofqui Fault to Maihue Lake.

This is explained by the great extent of the Patagonian Ice Sheet that covered most of the southern Andes and caught volcanic material such as ash and pyroclast.

[1] The earliest historical accounts of eruptions from the Mocho-Choshuenco complex may be those in Alonso de Ovalle's map Tabula Geographica Regni Chile from 1646.

According to a missionary from Quinchilca, who was interviewed by Vidal Gormaz in 1869, a strong noise followed by an earthquake was felt during one of the first days of November 1864.

The uppermost part of Mocho-Choshuenco is covered by an ice cap that surrounds the volcanic cone of Mocho and some flanks of Choshuenco.
