Sachsenburg is a market town on the Drava river in the Spittal an der Drau district in Carinthia, Austria. The municipality comprises the Katastralgemeinden of Sachsenburg and Obergottesfeld.
The origin of the name is uncertain: an affiliation with the far apart mediæval Duchy of Saxony has never been established; however the coat of arms probably awarded in the 16th century shows a Saxe, a kind of pan formerly used for gold prospecting within the nearby Hohe Tauern mountain range. Two fortresses at the strategically important narrow place of the Drava valley (Sachsenburger Klause) were first mentioned in a 1213 deed. Sachsenburg is documented as the administrative seat of a Salzburg exclave within the Duchy of Carinthia in 1292.
