Davos (Romansh: Tavau, archaic Italian: Tavate, local German pronunciation [daˈvoːs]) is a municipality in the district of Prättigau/Davos in the canton of Graubünden, Switzerland. It has a permanent population of 11,166 (2010). Davos is located on the Landwasser River, in the Swiss Alps, between the Plessur and Albula Range. At 1,560 m (5,120 ft), it is the highest city in Europe.

Davos is host to the World Economic Forum (WEF), an annual meeting of global political and business elites (often referred to simply as Davos) and the home of one of Switzerland's biggest ski resorts. At the end of every year it serves as the site of the annual Spengler Cup ice hockey tournament, hosted by the HC Davos local hockey team.

The current settlement of the Davos area started back in High Middle Ages with the immigration of Rhaeto-Romans. The village of Davos is first mentioned in 1213 as Tavaus. From about 1280 the barons of Vaz allowed German-speaking Walser colonists to settle down, and conceded them extensive self-administration rights, causing Davos to become the largest Walser settlement area in eastern Switzerland. Natives still speak a dialect that is atypical for Graubünden, showing similarities with German idioms of western parts of Switzerland, especially the Upper Valais.
