The Rätikon is a mountain range of the Central Eastern Alps, located at the border between Vorarlberg , Liechtenstein and Graubünden. It is the geological border between the Eastern and Western Alps and stretches from the Montafon as far as the Rhine . In the south, the Prättigau is its limit, and in the north, it is the Walgau. In the east, it borders the Silvretta groups. The Rätikon mountain range derives its name from Raetia , a province of the Roman Empire, named after the Rhaetian (Raeti or Rhaeti) people.

The classification of the Rätikon to the central Eastern Alps is based solely on geographic-geological traditions.
