The Schams (Romansh: (Val) Schons) is a section of the Hinterrhein valley in the Swiss canton of Graubünden.

The Schams is the central of the three valleys along the Hinterrhein. It is separated from the Rheinwald valley upstreams by the Rofla Gorge , and downstreams by the Viamala gorge from the Domleschg/Heinzenberg valley. The Posterior Rhine flows through the valley in a predominantly south-to-north direction and falls from a height of 1094 m at the outflow of Rofla Gorge, where the Val Ferrera flows in from the right, to 883 m at the Raniabrücke.

The Schams valley is bordered on both sides by mountain ranges of around 3000 m high. The highest peaks on the Western side are the Pizzas d'Anarosa (3000 m), the Bruschghorn (3056 m) and the prominent Piz Beverin (2998 m).
