Madame Sand is a 1917 play written by Philip Moeller, who subtitled it "a biographical comedy". It consists of three acts, with a medium-sized cast and moderate pacing. Most of the play's characters are historical, figures from the Romantic literary and musical world of the 1830s. Each act has only one scene and one setting. The subject is an episodic treatment of three love affairs conducted by George Sand, with Alfred de Musset, Pietro Pagello, and Frédéric Chopin.
