A lava cone is a type of volcano composed primarily of viscous lava flows. The volcanic cone can contain a convex profile due to the flank flows of viscous lava.

Lava cones are nearly unique to Bougainville Island in Papua New Guinea, within the Melanesia subregion of Oceania.
However, an unnamed group of seven lava cones is located in the Obul-Samarask upland of southern Georgia, in Western Asia. The cones are early Pleistocene to Holocene in age. Many of the craters have a well-preserved morphology. The tallest is 3,400 metres (11,200 ft).Tore, Bougainville island, Papua New Guinea
