Puyuhuapi Volcanic Group is a volcanic group of cinder cones located at the head of Puyuhuapi Channel, in the Aysén del General Carlos Ibáñez del Campo Region of Chile.

[6] The tectonic environment of the fault may impede the ascent of magma, thus the volcanoes have only small sizes.

[7] The cones may be extremely young,[1] one eruption with a volume of about 0.5 cubic kilometres (0.12 cu mi) may have occurred about 9,000 years ago based on stratigraphy, although the date is fairly uncertain.

[8] The glacial isostasy phenomena at the end of the last ice age may have triggered the magma ascent and thus eruptions.

[9] Presently, there is a cluster of earthquake activity close to the volcanic group.
