Descabezado Grande is a stratovolcano located in the Maule Region of central Chile. It is capped by a 1.4 km (0.9 mi) wide ice-filled caldera and named for its flat-topped form, as descabezado means "headless" in Spanish. A smaller crater about 0.5 km (0.3 mi) wide is found in the northeast part of the caldera, and it has active fumaroles.
The volcano is composed of andesite and rhyodacite lava flows along with pyroclastic flow deposits. It has a basal diameter of about 10 x 12 km ( 6 x 8 mi) and a total volume of about 30 km³ (7 mi³). Along with Cerro Azul, only 7 km to the south, it lies at the center of a 20 x 30 km (12 x 20 mi) volcanic field.
