Léonce Rosenberg (12 September 1879 in Paris – 31 July 1947 in Neuilly-sur Seine) was an art historian, art collector, publisher and one of the most influential French art dealers of the 20th century.
The son of an antique dealer Alexander Rosenberg and brother of the gallery owner Paul Rosenberg (21 rue de la Boétie, Paris), Léonce, a prominent gallery owner in Paris at the end of World War I, would become one of the world's major dealers of Modern art. Leaving the family-owned gallery in 1910 Léonce opened his own business called Haute Epoque at 19 rue de La Baume, Paris.
As an antiquarian Rosenberg began buying works by Cubist artists.
By 1914 his collection included works by Pablo Picasso, Jean Metzinger, Albert Gleizes, Auguste Herbin, and Juan Gris.
After serving in World War I (1916-1917) he pursued his interests and represented these and other artists, and by the end of the war opened a new show space, Galerie de L'Effort Moderne.
