Der Vampyr (The Vampire) is an opera (designated as a Romantische Oper) in three acts by Peter Josef von Lindpaintner. The German libretto by Cäsar Max Hegel was based on a work by Heinrich Ludwig Ritter, based in turn on a French melodrama by Charles Nodier, Pierre Carmouche and Achille de Jouffroy, ultimately traceable to the short story "The Vampyre" (1819) by John William Polidori, although Lindpaintner's libretto credits, erroneously, Lord Byron.
Other early 19th-century operas on the same theme were Silvestro de Palma's I vampiri (1812), Martin-Joseph Mengal's Le vampire (1826), and Heinrich Marschner's Der Vampyr of the same year as Lindpaintner's opera (1828).
