Billy Mitchell is a volcano located in the central part of the island of Bougainville, just northeast of the Bagana Volcano, in Papua New Guinea. It is a small pyroclastic shield truncated by a 2 km wide caldera filled by a crater lake.
The last two major eruptions were more than 400 (in 1580 AD ± 20 years) and 900 years ago. They were among the largest Holocene eruptions in Papua New Guinea. Both were explosive eruptions with a Volcanic Explosivity Index of at least 5. The eruption that occurred in 1580 AD ± 20 years produced pyroclastic flows and caused the formation of its caldera. The ignimbrite deposit from that eruption, which had a VEI of 6, extends 22 kilometres (14 mi) from the caldera to the coast, and its volume is around 10 cubic kilometres (2.4 cu mi).
The volcano is named for American general Billy Mitchell.
