Lucien Muhlfeld (4 August 1870, in Paris – 1 December 1902, in Paris) was a French novelist and dramatic critic. After completing his studies at the Lycée Condorcet, Muhlfeld entered the University of Paris, where he took the licentiate degrees in literature and law. He then engaged in literary work as a contributor to various periodicals. He became successively dramatic critic for L'Écho de Paris, La Revue Blanche, and the Revue d'Art Dramatique. He was the author of Le Mauvais Désir (1890), La Carrière d'André Tourette (1900), and L'Associée (1902)—all three novels dealing with Parisian life.
