Léon Bartholomé was a Belgian painter and engraver.

Léon Louis Bartholomé, born in Lille, rue du Faubourg-Notre-Dame, no. 257, on April 5, 1868, was the son of Joseph Gustave Bartholomé, a merchant born in Liège in 1818, and Rose Espérance Célina Mottin (1829-1898), a native of Hannut.

In 1893, he was one of the fifteen founding members of the Le Sillon movement, whose affiliates sought a return to traditional painting, to the Flemish realist tradition, and advocated painting that depicted nature directly. Their goal was naturalism.

At the 1903 Brussels Salon, he exhibited Intérieur en Provence, a watercolor, and an etching entitled En Famille. At the 1907 Brussels Salon, he presented Quai des pêcheurs à Ostende, a watercolor.

A member of the Société nationale des beaux-arts, he exhibited a watercolor, Fleurs, a drawing, Pêcheur de la Panne, and a painting, La Grand'place de Furnes, at the Salon des artistes français in 1929.

Léon Bartholomé died in Ypres on February 14, 1952, aged 83.
