Quetrupillán ("blunted", "mutilated"; also known as Ketropillán; the name is sometimes applied to the neighbouring Lanín volcano.) is a stratovolcano located in Los Ríos Region of Chile. It is situated between Villarrica and Lanín volcanoes, within Villarrica National Park. Geologically, Quetrupillán is located in a tectonic basement block between the main traces of Liquiñe-Ofqui Fault (to the west) and Reigolil-Pirihueico Fault (to the east).
The volcano consists of one stratovolcano with a summit caldera, and is constructed within a field of smaller centres and a larger caldera. It was active during the late Pleistocene; some large eruptions occurred during the Holocene as well.
