Fennimore und Gerda (subtitled Two Episodes from the Life of Niels Lyhne in Eleven Pictures, RT I/8) is a German-language opera with four interludes, by the English composer Frederick Delius. It is usually performed and recorded in English, as Fennimore and Gerda in a translation by Philip Heseltine. The German libretto, by the composer himself, is based on the novel Niels Lyhne by the Danish writer Jens Peter Jacobsen. In neither German nor English is the libretto highly regarded; rather, the work is considered an "orchestral opera", limited in its dramatic appeal but voluptuous and engaging in its instrumental texture.
