The Divisadero Group is a group of geological formations in the Magallanes Basin (Chile) or Austral Basin (Argentina) of northwestern Patagonia.

[1] The group is chiefly made up of pyroclastic rocks and lavas of the calc-alkaline magma series.

[1] Rocks are of andesite and rhyolite composition.

[2] In Chile, the formation crops out in Aysén Region[1] while in Argentina it can be found in Chubut Province.

[2] Tectonic movements during the Miocene have significantly deformed Divisadero Group.
