Henri-Jacques-Edouard Evenepoel (3 October 1872 – 27 December 1899) was a French-born Belgian artist whose most important works are associated with Fauvism.

Evenepoel entered the atelier of Gustave Moreau in 1893, which put him in contact with Henri Matisse, Georges Rouault, Albert Marquet, Edgar Maxence, Charles Milcendeau [fr], and Léon Printemps.

He showed four portraits at the Salon du Champ-de-Mars in 1895 and continued to exhibit there until his death.

Family and friends were the artist's preferred subjects; his full-length portraits, often against a neutral background, show the influence of Édouard Manet and James Abbott McNeill Whistler.

Though his early scenes had a somber palette, his paintings while in Algeria (where he first wintered during his solo exhibition) were very different in style, anticipating the bold colours of Fauvism (e.g., Orange Market, Blidah).
