Marie Maxime Cornu (July 16, 1843, in Orléans – April 3, 1901 in Paris) was a French botanist and mycologist. He was a younger brother of physicist Alfred Cornu (1841–1902). He studied at the École normale supérieure, and in 1872 received his doctorate in natural sciences. He served as aide-naturaliste at Museum National d'Histoire Naturelle in Paris, where from 1876 he worked as a lecturer of botany. From 1883 to 1901 he was chair of horticulture at the museum. In 1897 he was named president of the Société botanique de France. He is remembered for his research of cryptogams, as well as his investigations involving agents of plant diseases, in particular Phylloxera vastatrix, a pest that caused extensive damage to French vineyards and negatively affected wine production. In 1896 he circumscribed the botanical genus Schoenlandia (family Tecophilaeaceae). He is buried in the Pere Lachaise cemetery (Division 20), in Paris.
