Franz Friedrich Richard Genée (February 7, 1823 – June 15, 1895) was a Prussian born Austrian librettist, playwright, and composer. He is most famous for the libretto of Die Fledermaus, Johann Strauss II's most famous operetta. He co-wrote the libretto without having met top-billed librettist Karl Haffner, who constructed the new story based on a play by Henri Meilhac and Ludovic Halévy, which was considered too shocking to perform outside Paris. Genée, however, wrote the operetta's actual text and drew nothing from Haffner beyond the names of the characters.
