Libuše is a "festival opera" in three acts, with music by Bedřich Smetana. The libretto was originally written in German by Josef Wenzig, and was then translated into Czech by Ervín Špindler. In Czech historical myth, Libuše, the title character, prophesied the founding of Prague. The opera was composed in 1871–72 for the coronation of Franz Josef as King of Bohemia. This did not happen and Smetana saved Libuše for the opening of the National Theatre in Prague, which took place nine years later on 11 June 1881. After the destruction of the National Theatre in a fire, the same opera opened the reconstructed theatre in 1883. The first US performance was reported to have occurred March 1986, in a concert version at Carnegie Hall with Eve Queler and the Opera Orchestra of New York. In the UK, it was first staged by University College Opera in 2019.

Bedřich Smetana was a Czech composer who pioneered the development of a musical style that became closely identified with his people's aspirations to a cultural and political "revival". He has been regarded in his homeland as the father of Czech music. Internationally he is best known for his 1866 opera The Bartered Bride and for the symphonic cycle Má vlast, which portrays the history, legends and landscape of the composer's native Bohemia. It contains the famous symphonic poem "Vltava", also popularly known by its German name "Die Moldau".
