Don Juan is a 1812 short story by E. T. A. Hoffmann, which was first published on 31 March 1813 in the Allgemeine musikalische Zeitung and later republished in Hoffmann's 1814 collection Fantasiestücke in Callots Manier.[1]
The story is told in the first person by a traveller who describes his experience watching Mozart's opera Don Giovanni in a theatre adjacent to his hotel.
