This is a list of active and extinct volcanoes in Chile.

A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, ash and gases to escape from below the surface. The word volcano is derived from the name of Vulcano island off Sicily which in turn, was named after Vulcan, the Roman god of fire.

Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust (called "non-hotspot intraplate volcanism"), such as in the African Rift Valley, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America and the European Rhine Graben with its Eifel volcanoes.

Chaitén is a volcanic caldera 3 kilometres (1.9 mi) in diameter, 17 kilometres (10.6 mi) west of the elongated, ice-capped Michinmahuida volcano, and 10 kilometres (6 mi) northeast of Chaitén town in the Gulf of Corcovado, in southern Chile. The most recent eruptive phase of the volcano began on May 2, 2008, and is ongoing. According to the Global Volcanism Program, radiocarbon dating of older tephra from the volcano suggests that its last previous eruption was in 7420 BC plus or minus 75 years.

The caldera rim reaches 1,122 metres (3,681 ft) above sea level. Prior to the current eruption, it was mostly filled by a rhyolite obsidian lava dome that reached a height of 962 metres (3,156 ft), partly devoid of vegetation. Two small lakes occupied the caldera floor on the west and north sides of the lava dome.

The translucent grey obsidian which had erupted from the volcano was used by pre-Columbian cultures as a raw material for artifacts and has been found as far away as 400 km to the south and north, for example in Chan-Chan.

Chile, officially the Republic of Chile (Spanish: República de Chile [reˈpuβlika ðe ˈʧile]), is a country in South America occupying a long, narrow coastal strip between the Andes mountains to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. With Ecuador it is one of two countries in South America which do not border Brazil. The Pacific coastline of Chile is 6,435 kilometres. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas and Easter Island. Chile also claims about 1,250,000 square kilometres (480,000 sq mi) of Antarctica, although all claims are suspended under the Antarctic Treaty.

Chile's unusual, ribbon-like shape—4,300 kilometres (2,700 mi) long and on average 175 kilometres (109 mi) wide—has given it a varied climate, ranging from the world's driest desert—the Atacama—in the north, through a Mediterranean climate in the centre, to a rainy temperate climate in the south. The northern desert contains great mineral wealth, principally copper. The relatively small central area dominates in terms of population and agricultural resources, and is the cultural and political center from which Chile expanded in the late 19th century, when it incorporated its northern and southern regions. Southern Chile is rich in forests and grazing lands and features a string of volcanoes and lakes. The southern coast is a labyrinth of fjords, inlets, canals, twisting peninsulas, and islands.
