Mount Ragang is located in the southern part of Lanao del Sur in the Bangsamoro autonomous region.

Ragang has an elevation of 2,815 metres (9,236 ft) and a base diameter of 32 km (20 mi).

It is one of the active volcanoes in the Philippines, which are all part of the Pacific ring of fire.

The Philippine Institute of Volcanology and Seismology lists eight eruptions, with the last one occurring in July 1916.

However, the Smithsonian Institution's Global Volcanology Programs, citing the Catalog of Active Volcanoes of the World (Neumann van Padang, 1953), suggests that some eruptions attributed to nearby Makaturing were those of Ragang.
