Flemish Expressionism, also referred to as Belgian Expressionism, was one of the dominant art styles in Flanders during the interbellum. Influenced by artists like James Ensor and the early works of Vincent van Gogh, it was a distinct contemporary of German Expressionism. Contrary to the more rebellious and erotic nature of many German Expressionist works, the Flemish art of the School of Latem was more oriented towards the farming life, and was expressed in earthy colours and vigorous brushwork. It was also in general more oriented towards France and Brussels than to Germany, and incorporated elements of Fauvism and Cubism, for example the interest in "primitive" art, of both the ethnic and folk traditions. Flemish Expressionists like Spilliaert were more influenced by Ensor and Symbolism, or like Wouters were closer to the vibrant colours used by the Fauvists. The main proponents were Gust De Smet, Constant Permeke and Frits Van den Berghe.

Constant Permeke was a Belgian painter and sculptor who is considered the leading figure of Flemish Expressionism.
