Hohenthurn (Slovene: Straja vas) is a municipality in the district of Villach-Land in the Austrian state of Carinthia.

The municipal area stretches on the northern slope of the Carnic Alps, close to the border with Italy.

The municipality was the site of a prehistoric Hallstatt settlement as well as of a Roman watchtower, which is depicted in the coat of arms.

Nevertheless, Hohenthurn (from German hoher Turm, i.e. "high tower"), first mentioned in a 1253 deed as Göströsdorf, probably derived its name from the steeple of the Gothic St. Cyriacus Church.

Since the medieval Slavic settlement of the Eastern Alps, the area is a centre of Slovene tradition and customs.
