The Schiller Theater is a theatre building in Berlin, Germany. It is located in the central Charlottenburg district at Bismarckstraße No. 110 near Ernst-Reuter-Platz.
Opened in 1907, the building served as second venue of the Prussian State Theatre company in the 1920s and 1930s. After post-war rebuilding, it was the main stage of the Berlin State Theatres from 1951 until in 1993 the City Senate decided to close it for financial reasons. Since then, it is rented out for theatre performances and other events, and is currently used by the Berlin State Opera as an interim venue during extensive renovation work.
