Oberdrauburg is a market town in the district of Spittal an der Drau at the western rim of the Austrian state of Carinthia.

The Drava or Drave, historically known as the Dravis or Dravus, is a river in southern Central Europe. With a length of 710km, or 724km, if the length of its Sextner Bach source is added, it is the fifth or sixth longest tributary of the Danube, after the Tisza, Sava, Prut, Mureș and likely Siret. The Drava drains an area of about 40,154 square kilometers. Its mean annual discharge is seasonally 500m³/s to 670m³/s. Its source is near the market town of Innichen, in the Puster Valley of South Tyrol, Italy. The river flows eastwards through East Tyrol and Carinthia in Austria into the Styria region of Slovenia. It then turns southeast, passing through northern Croatia and, after merging with its main tributary the Mur, forms most of the border between Croatia and Hungary, before it joins the Danube near Osijek, in Croatia.
