The Aarmassif or Aaremassif (German: Aarmassiv) is a geologic massif in the Swiss Alps. It contains a number of large mountain chains and parts of mountain chains.
The massif is named after the Aar, a river that has its source in the Aarmassif.
The Aarmassif crops out in the eastern part of the Bernese Alps and the Lepontine Alps, roughly form Leukerbad in the west to the Tödi in the east. Further east the massif only appears in small windows like the Vättner window between Gigerwald and Vättis in Sankt Gallen and at the Limmerensee in the same canton.
