Vals (locally pronounced [ˈvals]) is a village and a municipality in the Surselva Region in the canton of Graubünden in Switzerland.

In the 13th century, the Walser were driven from the canton of Wallis in south-west Switzerland into the Valser valley.

The Walser also brought with them the Valliser style of house, which uses more wood than stone and has triangular roofs.

In 1457 the German-speaking population was forbidden from purchasing land or marrying in the neighboring village of Tersnaus.

After 1776, St. Martin's village church had a German-speaking Prebend though in 1868 it fell back under the authority of Tersnaus.

Of the rest of the land, 0.5% was settled (buildings or roads) and the remainder (57.4%) was non-productive (rivers, glaciers or mountains).

Zervreilasee is a reservoir in the valley, formed by a dam on the Vals Rhine.
