This article is about the volcano. For the city named after the volcano, see Mount Hagen.

Mount Hagen is the second highest volcano in Papua New Guinea and on the Australian continent, ranking behind only its neighbour Mount Giluwe which is roughly 35 kilometres (22 mi) to the southwest. It is located on the border between the Western Highlands and Enga Provinces, about 24 kilometres (15 mi) northwest of the city of Mount Hagen which is named after it.

Mount Hagen is an old stratovolcano which has been heavily eroded during several Pleistocene glaciations. The maximum extent of the glaciers on Hagen was less than half that on the much higher Mount Giluwe, covering an area of up to 50 km² (20 mi²) and extending down below 3,400 m (11,000 ft).^[2]
