La fille mal gardée (French pronunciation: [la fij mal ɡaʁde]; French for The Wayward Daughter, literal translation: "The Poorly Guarded Girl" and also known as The Girl Who Needed Watching) is a comic ballet presented in two acts, inspired by Pierre-Antoine Baudouin's 1765 painting, La réprimande/Une jeune fille querellée par sa mère. The ballet was originally choreographed by the ballet master Jean Dauberval to a pastiche of music based on fifty-five popular French airs. The ballet was premiered on 1 July 1789 at the Grand Théâtre de Bordeaux in Bordeaux, France under the title Le ballet de la paille, ou Il n'est qu'un pas du mal au bien (The Ballet of Straw, or There is Only One Step from Bad to Good).
La fille mal gardée is one of the oldest and most important works in the modern ballet repertory, having been kept alive throughout its long performance history by way of many revivals. The work has undergone many changes of title and has had no fewer than six scores, some of which were adaptations of older music.
