Jules Hénault was a French painter, caricaturist, lithographer, and illustrator with anarchist leanings.

During the 1880s and 1890s, Jules Hénault drew educational comic strips for Pellerin and Maison Quantin.

Shortly before 1900, his collaborations took a radical turn. Alongside fellow caricaturists Steinlen, Hermann-Paul, Huard, Léandre, Camara, and Luce, he joined " this category of progressive intellectuals who believed they could win over part of the bourgeoisie to the ideas of social emancipation, sharing the same belief in a socialism of education, close to Péguy and the Cahiers de la Quinzaine and reflecting the Dreyfusard spirit."

He published in anarchist periodicals such as Les Temps Nouveaux, Le Libertaire, l'Almanach illustré de la révolution (1902-1909), and Jean-Pierre. He also contributed drawings to La Caricature and to the publisher Schwarz for L'Assiette au beurre (from 1901 to 1907) and La Calotte, as well as for La Science en images.

He illustrated works by Ernest Girault, Jean Most, and Pierre Kropotkin.
