The Burgtheater, originally known as K.K. Theater an der Burg, then until 1918 as the K.K. Hofburgtheater, is the national theater of Austria in Vienna. It is the most important German-language theater and one of the most important theatres in the world. The Burgtheater was opened in 1741 and has become known as "die Burg" by the Viennese population; its theater company has created a traditional style and speech typical of Burgtheater performances.

Vienna is the capital, most populous city, and one of nine federal states of Austria. It is Austria's primate city, with just over two million inhabitants. Its larger metropolitan area has a population of nearly 2.9 million, representing nearly one-third of the country's population. Vienna is the cultural, economic, and political center of the country, the fifth-largest city by population in the European Union, and the most-populous of the cities on the Danube river.
