The Margraviate of Austria was a southeastern frontier march of the Holy Roman Empire created in 976 out of the territory on the border with the Kingdom of Hungary. Originally under the overlordship of the Dukes of Bavaria, it was ruled by margraves of the Franconian Babenberg dynasty. It became an Imperial State in its own right, when the Babenbergs were elevated to Dukes of Austria in 1156.

In contemporary Latin, the entity was called the marcha Orientalis ("Eastern march"), marchia Austriae, or Austrie marchionibus. The Old High German name Ostarrîchi first appeared on a famous deed of donation issued by Emperor Otto III at Bruchsal in November 996. The phrase regione vulgari vocabulo Ostarrîchi, that is, "the region commonly called Ostarrîchi", probably only referred to some estates around the manor of Neuhofen an der Ybbs; nevertheless the term Ostarrîchi is linguistic ancestor of the German name for Austria, Österreich.

Later the march was also called the Margraviate of Austria (Markgrafschaft Österreich) or the Bavarian Eastern March (Bayerische Ostmark, the second word being a German translation of marcha orientalis, though no example of this usage in relation to Austria is known before the 19th century) to differentiate it from the Saxon Eastern March (Sächsische Ostmark) in the northeast. During the Anschluss period of 1938–45 the Nazi authorities tried to replace the term "Austria" with Ostmark.
