Charles Simon Favart was a French dramatist.
Born in Paris, the son of a pastry-cook, he was educated at the college of Louis-le-Grand, and after his father's death he carried on the business for a time. His first success in literature was La France delivrée par la Pucelle d'Orléans, a poem about Joan of Arc which obtained a prize of the Académie des Jeux Floraux. After the production of his first vaudeville, Les Deux Jumelles, circumstances enabled him to relinquish business and devote himself entirely to the drama. He provided many pieces anonymously for the lesser theatres, and first put his name to La Chercheuse d'esprit, which was produced in 1741.
Among his most successful works were Annette et Lubin, Le Coq du milage, Ninette à la cour, Les Trois Sultanes and L'Anglais de Bordeaux. Favart became director of the Opéra-Comique, and in 1745 married Marie Justine Benoîte Duronceray, a beautiful young dancer, singer and actress, who as "Mlle Chantilly" had made a successful début the year before. By their united talents and labours, the Opéra-Comique rose to such a height of success that it aroused the jealousy of the rival Comédie-Française and was suppressed.
