Rusalka (pronounced [ruˈsalka] ( listen)), Op. 114, is an opera ('lyric fairy tale') by Antonín Dvořák. The Czech libretto was written by the poet Jaroslav Kvapil (1868–1950) based on the fairy tales of Karel Jaromír Erben and Božena Němcová. A Rusalka is a water sprite from Slavic mythology, usually inhabiting a lake or river. Rusalka is one of the most successful Czech operas, and represents a cornerstone of the repertoire of Czech opera houses.
