Jean-Baptiste-Antoine Guillemet (June 30, 1843 in Chantilly (Oise) – May 19, 1918 in Mareuil-sur-Belle (Dordogne)) was a French renowned landscape painter and longtime Jury member of the Salon des Artistes Francais.

By 1864 Guillemet had also encountered Édouard Manet, Alfred Stevens, Camille Pissarro, Claude Monet, Gustave Courbet, and Paul Cézanne and later, Henri Fantin-Latour, Edgar Degas and Jean-Frédéric Bazille.

Like almost every ambitious young artist Guillemet realized that he needed to make his mark at the Paris Salon, and in 1865 exhibited L'Etang de Bat (Isère).

Ready to produce large works, unlike many of his contemporaries who sought a more immediate effect, he painted several views of the capital, often using the Seine with its bustling traffic as a central motif.

At the Salon of 1874 Guillemet's ambitious entry was a nine-foot painting titled Bercy en décembre,[5] which was praised by both critics and the public and which was promptly purchased by the state for the Musée du Luxembourg, then the national museum for contemporary art.
