This is a list of active, dormant and extinct volcanoes located beyond planet Earth. They may be designated mons (mountain), patera (an irregular crater) or tholus (small mountain or hill) in accordance with the International Astronomical Union's rules for planetary nomenclature.

Volcanoes on Io, a moon of the planet Jupiter, are believed to eject sulfur or possibly sulfur dioxide.

Lava-flooded craters and large expanses of smooth volcanic plains on Mercury

Many of Mercury's basins contain smooth plains, like the lunar mare, that are believed likely to be filled with lava flows. Collapse structures possibly indicative of volcanism have been found in some craters.[1] Eleven volcanic domes were identified in Mariner 10 images, including a 1.4-km high dome near the centre of Odin Planitia.[2]
