Eine Nacht in Venedig (A Night in Venice) is an operetta in three acts by Johann Strauss II. Its libretto was by F. Zell and Richard Genée based on Le Château Trompette by Eugène Cormon and Richard Genée. The farcical, romantic story involves several cases of mistaken identity. The piece premiered in 1883 in Berlin and then Vienna. It became one of Strauss's three most famous stage works and has been seen in New York, London and elsewhere, and has been adapted for film.
