Andeer is a municipality in the Viamala Region in the Swiss canton of the Grisons . In 2009, Clugin and Pignia merged into Andeer.

Roman coins discovered near Andeer indicate that there was a Roman presence in the area during the time of the Roman province of Raetia (from 15 BC). The name of the settlement was presumably Lapidaria, and it would have already been an important stop on the road from Italy.

Andeer is first mentioned in 1208 as Anders.

Around 1820, roads were built over the Splügen Pass and the San Bernardino Pass .
