Mountains at Collioure

André Derain was a French artist, painter, sculptor and co-founder, with Henri Matisse, of Fauvism. His paintings of 1905–1906 are characterized by riotous colourism in the Fauve style. By 1910, however, his work had become more austere as a result of his study of Cézanne and the old masters. After the First World War, Derain became one of the leaders of the new classicism in the arts known as the Return to order.

Mountains at Collioure is a 1905 painting by French painter André Derain. It was made while he was working with Henri Matisse at the fishing port of Collioure, in France. It has been in the National Gallery of Art in Washington, D.C. since John Hay Whitney, the previous owner, died in 1982. The work features long strokes of colours such as bright green, blue, mauve and pink. The entire scene is under a jade and turquoise sky.
