La Marjolaine is an opéra bouffe in three acts, with music by Charles Lecocq and words by Eugène Leterrier and Albert Vanloo, the third collaboration by the three. It opened at the Théâtre de la Renaissance, Paris on 3 February 1877 and had a fairly successful run of 117 performances. The work was staged in continental Europe, Britain and the Americas over the next few years.
The piece is set in 16th century Flanders; it depicts a deceitful, and ultimately unsuccessful, attempt to damage a virtuous woman's reputation. The central role was taken in the original production by Jeanne Granier, who created the leading parts in several Lecocq operas of the 1870s.
