Antoine-Fortuné Marion (10 October 1846 – 22 January 1900) was a French naturalist with interests in geology, zoology, and botany. He was also a competent amateur painter. A school friend of Paul Cézanne's in Aix-en-Provence, Marion went on to become professor and director of the Natural History Museum in Marseille. Cézanne painted his portrait in 1866–1867 at the Bastide du Jas de Bouffan. He was a founder of the publication "Annales du Musée d'histoire naturelle de Marseille". His painting The Village Church now belongs to the Fitzwilliam Museum.
