Der Bärenhäuter is an 1899 German-language opera in three acts by Siegfried Wagner based on the German folk tale "Der Bärenhäuter" ("Bearskin"). As with most of Siegfried Wagner's operas it is more influenced by his teacher Humperdinck than his father Richard Wagner's operas. Siegfried Wagner composed the music and wrote the libretto for his opera which takes place during the Thirty Years' War near Bayreuth.
