Cerro Walther Penck (also known as Cerro Cazadero or Cerro Tipas) is a massive complex volcano in the Andes, located in northwestern Argentina, Catamarca Province, Tinogasta Department, at the Puna de Atacama. It is just southwest of Ojos del Salado, the highest volcano in the world. Walther Penck itself is perhaps the third highest active volcano in the world.

There are reports of fumarolic activity, and de Silva and Francis (1991) considered that the volcano was last active in the Holocene. Crater lakes with a smell of sulfur were reported in 2013. The Tipas-Cerro Bayo complex was active 2.9-1.2 million years ago with dacites and rhyolites. Magma composition is typical for Andean stratovolcanoes. Tomographic studies of the underlying crust indicate a pattern of seismic attenuation beneath Tipas.
