Hulda is an opera by César Franck to a French libretto by Charles Grandmougin. It is set in 11th-century Norway, and is based on the play (1858) by Norwegian writer Bjørnstjerne Bjørnson. The complete opera contains a prologue, three acts and an epilogue, albeit the world premier recording by Naxos has five acts. It was composed between 1879 and 1885.
