Descabezado Grande (also Cerro Azul or Quizapu[1]) is a stratovolcano located in the Maule Region of central Chile.

It is capped by a 1.4-kilometre-wide (0.9 mi) ice-filled caldera and named for its flat-topped form, as descabezado means "headless" in Spanish.

A smaller crater about 500 metres (1,600 ft) wide is found in the northeast part of the caldera, and it has active fumaroles.

Along with Cerro Azul, 7 kilometres (4.3 mi) to the south, it lies at the center of a 20-by-30-kilometre (12-by-19-mile) volcanic field.
