Henri Victor Gabriel Le Fauconnier (July 5, 1881 – December 25, 1946) was a French cubist painter born in Hesdin.

Henri Le Fauconnier studied in the studio of Jean-Paul Laurens, then in the Academie Julian. He exhibited at the Salon des Indépendants in 1905, implementing bold colors in line with Henri Matisse. He moved to Brittany in 1907 and painted the rocky landscapes of Ploumanac'h, characterized by chastened tones of brown and greens with thick outlines delimiting the simplified forms. He explored a personal style and put it into practice; painting nudes or portraits (such as that of the poet Pierre Jean Jouve in 1909 (Musée National d'Art Moderne). Back in Paris, he mingles with the artistic and literary gathered around Paul Fort at the Closerie des Lilas in Montparnasse.

At the 1909 Salon d’Automne Le Fauconnier exhibited alongside Constantin Brancusi, Jean Metzinger and Fernand Léger.

Louis Vauxcelles, in his review of the 1910 Salon des Indépendants, made a passing and inaccurate reference to Le Fauconnier, Jean Metzinger, Albert Gleizes, Robert Delaunay and Fernand Léger, as "ignorant geometers, reducing the human body, the site, to pallid cubes."
