Léon Laya (c.1810 in Paris – 5 September 1872 in Paris) was a 19th-century French playwright. The académicien Jean-Louis Laya was his father. Léon Laya was the author of a number of successful comedies, alternating between the delicacy or purity of the idea and the vivacity of the form : Une Maîtresse anonyme, in 2 acts (1812) ; la Peau du lion, in 2 acts (1814) ; les Cœurs d’or, in 3 acts, with Prémaray (Gymnase, 1854) ; les Jeunes gens, in 3 acts, free and independent adaptation of Terence's Adelphoe (Théâtre-Français, 1855) ; le duc Job, in 4 acts, one of the most sustained successes of the Théâtre-Français (1859) ; la Loi du cœur (Théâtre-Français, 1862), etc.
