Mt. Sisa is a heavily eroded Pleistocene stratovolcano in Hela, Papua New Guinea. The taller of the mountain's two main peaks is estimated to be 2,650 metres (8,690 ft) high. The northern peak has a communications mast. The epicentre of the 2018 Papua New Guinea earthquake was on the mountain's northern foothills.
A tiny species of frogs, Choerophryne allisoni, is only known from its type locality on Mount Sisa.
