Mount Tangkoko is a stratovolcano in the north of Sulawesi island in Indonesia. Its summit has an elongated deep crater. On the east flank, there is a flat lava dome Batu Angus. Historical records only show eruptions in the nineteenth century.

The Tangkoko Batuangus Nature Reserve, in the northern part of Sulawesi island, is named after the volcano and is a refuge for such species as the Celebes crested macaque and spectral tarsier.
