Claude-Henri de Fusée, abbé de Voisenon (8 July 1708 – 22 November 1775) was a French playwright and writer.
Born at the château de Voisenon near Melun, he was only ten when he addressed an epistle in verse to Voltaire, who asked the boy to visit him. They remained friends for fifty years. Voisenon made his début as a dramatist with L’Heureuse resemblance in 1728, followed in 1739 by a three-act comedy L’École du monde at the Théâtre Français. This was preceded by a verse prologue, L’Ombre de Molière, and a month later Voisenon produced a criticism of his own piece in Le Retour de l’ombre de Molière.
