Werther is an opera (drame lyrique) in four acts by Jules Massenet to a French libretto by Édouard Blau, Paul Milliet and Georges Hartmann (who used the pseudonym Henri Grémont). It is loosely based on the German epistolary novel The Sorrows of Young Werther by Johann Wolfgang von Goethe, which was based both on fact and on Goethe's own early life. Earlier examples of operas using the story were made by Kreutzer (1792) and Pucitta (1802).
