Leonardo Dudreville (4 April 1885 – 13 January 1975) was a Venetian-born Italian painter.
He studied at the Brera Academy in Milan from 1903 to 1905 and joined the Coenobium, a group of young artists belonging to the Scapigliatura movement, in Monza together with his friend Anselmo Bucci.
After a stay in Paris (1906–07), his Divisionist style brought him into contact with Alberto Grubicy's gallery.
In close contact with the critic Margherita Sarfatti in the years following World War I, he took part in the Venice Biennale (13th Esposizione Internazionale d’Arte di Venezia) in 1922, and in the following year was one of the group of Sette pittori del Novecento who started the Novecento Italiano art movement exhibiting at the Galleria Pesaro in Milan.
Relations between members of the Novecento movement were not always smooth, as shown by his participation in their first group exhibition in 1926 but not in the second in 1929.
