Pacana je najvažnija kaldera u istoimenom kompleksu u čileanskoj regiji Antofagasta, istočno od slaništa Salar de Atacama. Kompleks La Pacana dio je vulkanskog kompleksa Altiplano-Puna. Tromeđa Čilea, Bolivije i Perua nalazi se sjeveroistočno od ovog vulkana, dok je na jugozapadu slanište Salar Aguas Calientes. Dimenzije depresije kaldere iznose 70 x 35 km. Velika erupcija prije oko 4 miliona godina proizvela je 2.500 km3 tefre.
