Louis Anquetin (January 26, 1861 - August 19, 1932) was a French painter.
Anquetin was born in Etrepagny, France. In 1882, he came to Paris and began studying art at Léon Bonnat's studio, where he met Henri de Toulouse-Lautrec. The two artists later moved to the studio of Fernand Cormon, where they befriended Émile Bernard and Vincent van Gogh.
Around 1887, Anquetin and Bernard developed a painting style that used flat regions of color and thick, black contour outlines. This style, named cloisonnism by critic Edouard Dujardin, was inspired by both stained glass and Japanese ukiyo-e. One example of this can be seen in Avenue de Clichy: Five O’Clock in the Evening, which is said to have inspired Van Gogh in painting his famous Cafe Terrace at Night.
He eventually fell from the public's eye after abandoning the modern movements, opting instead to study the methods of the Old Masters. Thus, Anquetin's works following the mid-1890s, such as Rinaldo and Armida, were especially Rubensian and allegorical in nature. In 1907, he met Jacques Maroger, a young artist who shared his interest, with whom he collaborated.
Later in life, Anquetin wrote a book on Rubens, which was published in 1924. He died in Paris.
