La Grande-Duchesse de Gérolstein is an opéra bouffe, in three acts and four tableaux by Jacques Offenbach to an original French libretto by Henri Meilhac and Ludovic Halévy. The story is a satirical critique of unthinking militarism and concerns a spoiled and tyrannical young Grand Duchess who learns that she cannot always get her way.

Jacques Offenbach 20 June 1819 – 5 October 1880) was a German-born French composer, cellist and impresario. He is remembered for his nearly 100 operettas of the 1850s to the 1870s, and his uncompleted opera The Tales of Hoffmann. He was a powerful influence on later composers of the operetta genre, particularly Franz von Suppé, Johann Strauss Jr. and Arthur Sullivan. His best-known works were continually revived during the 20th century, and many of his operettas continue to be staged in the 21st. The Tales of Hoffmann remains part of the standard opera repertory.
