Waltensburg/Vuorz is a former municipality in the Surselva Region in the canton of Graubünden in Switzerland . On 1 January 2018 the former municipalities of Andiast and Waltensburg/Vuorz merged into the municipality of Breil/Brigels .

Waltensburg/Vuorz was first mentioned in 765 as Vorce. The German name of Waltensburg is first mentioned in 1209 as Waltramsburg, which was an older name of the castle Jörgenberg. While the Romansh speaking population used the older, Romansh name of Vorce (meaning: "a river fork") the former name of the castle moved to include the village. At about the same time, the castle came to be known as Jörgenberg from the name of the nearby early medieval fortified Church of St George.
