San Pablo is a dormant volcano located in the Antofagasta Region of Chile, near the Bolivia border. It is joined to the younger San Pedro volcano by a high col.

San Pablo was active in pre-glacial times. After that period, glaciations formed a girdle of moraines and the mountain was covered by ash fall from neighbouring San Pedro.[4] Its central crater was eroded and a glacier formed inside. The volcano itself is formed by three groups of andesite lavas which variously contain pyroxene or hornblende; these groups are known as the Lower Group, the Middle Group and the Summit Group.[5]
