Osorno Volcano is a 2,652-metre (8,701 ft) tall conical stratovolcano lying between Osorno Province and Llanquihue Province, in Los Lagos Region of Chile. It stands on the southeastern shore of Llanquihue Lake, and also towers over Todos los Santos Lake. Osorno is known worldwide^{[citation needed]} as a symbol of the local landscape, and is noted for its similar appearance to Mount Fuji.

Osorno is one of the most active volcanoes of the southern Chilean Andes, with 11 historical eruptions recorded between 1575 and 1869. The basalt and andesite lava flows generated during these eruptions reached both Llanquihue and Todos los Santos Lakes. The upper slopes of the volcano are almost entirely covered in glaciers despite its very modest altitude and latitude, sustained by the substantial snowfall in the very moist maritime climate of the region.

Osorno sits on top of a 250,000-year-old eroded stratovolcano, La Picada, with a 6-km-wide caldera.^[2]
