Austrian Silesia (German: Österreichisch Schlesien; Czech: Rakouské Slezsko; Polish: Śląsk Austriacki), officially the Duchy of Upper and Lower Silesia (German: Herzogtum Ober- und Niederschlesien; Czech: Vévodství Horní a Dolní Slezsko), was an autonomous region of the Kingdom of Bohemia and the Austrian Empire, from 1867 a Cisleithanian crown land of Austria-Hungary. It is largely coterminous with the present-day region of Czech Silesia, and was, historically, part of the larger Silesia region.

Austrian Silesia consisted of two territories, separated by the Moravian land strip of Moravská Ostrava between the Ostravice and Oder rivers.

The area east of the Ostravice around Cieszyn reached from the heights of the Western Carpathians (Silesian Beskids) in the south, where it bordered with the Kingdom of Hungary, along the Olza and upper Vistula rivers to the border with Prussian Silesia in the north. In the east the Biała river at Bielsko separated it from the Lesser Polish lands of the Polish–Lithuanian Commonwealth, incorporated into the Austrian Kingdom of Galicia and Lodomeria upon the First Partition of Poland in 1772.
