Reichenau (Romansh: La Punt) is a village in the municipality of Tamins in the Canton of Graubünden, Switzerland, where the two Rhine tributaries Vorderrhein and Hinterrhein meet, forming the Alpine Rhine.

The name originates from the Benedictine Abbey of Reichenau on Reichenau Island in Lake Constance which owned properties in this area during the Middle Ages.

The monastery was founded in 724 and drew to itself abbots with connections to the highest Carolingian and Ottonian society; it housed a school, and a famous scriptorium.

In the 14th century the first bridges were built over the Rhine tributaries.

A roadhouse was built 1570 to collect the bridge toll.
