Werdenberg was a county of the Holy Roman Empire, within the Duchy of Swabia, situated on either side of the Alpine Rhine, including parts of what is now St. Gallen (Switzerland), Liechtenstein, and Vorarlberg (Austria). It was partitioned from Montfort in 1230. In 1260, it was divided into Werdenberg and Sargans.
