Schlosstheater Schwetzingen (Schwetzingen palace theater) is a court theater in Schwetzingen, Baden-Württemberg, Germany. The historic building, opened in 1753, is part of Schloss Schwetzingen and since 1952 the principal venue of the Schwetzingen Festival. It is also called Hoftheater (court theater), Hofoper (court opera), and Comoedienhaus (comedy house). The frequently applied name Rokokotheater (Rococo theater) is misleading, because it shows also neoclassical elements, added in 1762.
