Léon Printemps (Paris, 1871 – Paris, 1945) was a French painter best known for his portraits and landscapes. Born in Paris to a family from Lille, he entered the École nationale des Beaux-Arts in 1892 and attended the workshop of Gustave Moreau until the master's death in 1898. In these years his work largely belonged to the Symbolist movement, with poetic and mythological visions and a sensual treatment of the female nude.
He soon built a reputation as a portraitist, receiving commissions from figures such as Sully Prudhomme, the first Nobel laureate in Literature, and Prince Yusupov. He often painted his family in an intimate manner. Drawn to Flemish and Dutch masters, he travelled to Belgium and the Netherlands, and after the First World War he painted seascapes and local figures on the Vendée coast, Noirmoutier and the île d'Yeu.
Most of his surviving work is held in French public collections, such as the Musée Lambinet in Versailles and the Musée départemental breton in Quimper. He died in 1945 in his studio on rue Furstenberg in Paris.
