Mount Bosavi is a mountain in the Southern Highlands province, Papua New Guinea. It is the collapsed cone of an extinct volcano on the Great Papuan Plateau, part of the Kikori River basin. The crater is approximately 4 km wide and 1 km deep; it is home to a number of unique species.
The people living just north of the mountain refer to themselves as Bosavi kalu (people of Bosavi) and divide into four culturally identical but linguistically marked groups, the Kaluli, Ologo, Walulu, and Wisesi. Collectively they are often referred to as Bosavi kalu ("men of Bosavi").
