The Mark an der Drau (German for "March on the (river) Drava") was a historical territory of the Holy Roman Empire and its predecessors during the Middle Ages.

It came into being during the second half of the 10th century, covering an area from the eastern border of the Carolingian Carantanian Gaugrafschaft of Jauntal [de] (that is, the Drava valley between the mouth of the Vellach and Schwabegg) to Pettau (modern Ptuj) in the territory of Friedau (Ormož).

The territories west of this line — Mahrenberg (Radlje ob Dravi), Hohenmauthen (Muta), Saldenhofen (Vuzenica) and Windischgraz (Slovenj Gradec) — still belonged in the narrow sense to the Duchy of Carinthia (from 976).

The eastern border with the Kingdom of Hungary was poorly defined; the lordship of Ankenstein (Borl) was an autonomous territory (Allod) until the reign of Maximilian I; Polstrau (Središče ob Dravi) on the other hand was a Hungarian fief of the Archbishopric of Salzburg until 1803.

In 985 due to the intervention of Duke Henry of Carinthia, Otto III gave count Rachwin 15 Königshufen (a unit of land equivalent to the Scottish and English Oxgang) in Rosswein (Razvanje, south of Maribor).

Until about 1005 the territory of Aribo, Markgraf im Jaunetal (Margrave in the Jaun valley) was administered[4] by a brother of bishop Albuin of Brixen and member of the Aribonids, and who held large amounts of lucrative property in Bavaria, Salzburg, Carinthia and Styria (namely around Leoben and Straßgang), as well as in the Drava and Sann (Savinja) marches.

[5] In 1362 the territory of Windischgraz (Slovenj Gradec), which had been a possession of the Patriarchate of Aquileia since 1228 (and before that the Counts of Andechs; see Henry II, Margrave of Istria), fell to the Habsburgs, but belonged neither to Styria nor Carinthia.
