Uturuncu is a dormant volcano in the Sur Lípez Province of Bolivia. It is high, has two summit peaks, and consists of a complex of lava domes and lava flows with a total volume estimated to be . It bears traces of a former glaciation, even though it does not currently carry glaciers. Volcanic activity took place during the Pleistocene epoch and the last eruption was 250,000 years ago; since then Uturuncu has not erupted but active fumaroles occur in the summit region, between the two summits.

The volcano rises within the Altiplano–Puna volcanic complex, a larger province of large volcanoes and calderas which over the last few million years (mya) have emplaced about of ignimbrites in sometimes very large eruptions. Underneath it lies the so-called Altiplano–Puna magmatic body, a large sill formed by partially molten rocks.
