Charles Victor Naudin (14 August 1815 in Autun – 19 March 1899 in Antibes) was a French naturalist and botanist.
Naudin studied at Bailleul-sur-Thérain in 1825, at Limoux, and at the University of Montpellier from which he graduated in 1837. The following year he was working as a private tutor; he obtained his doctorate in 1842. He taught until 1846, when he joined the herbarium of the National Museum of Natural History. He collaborated with Augustin Saint-Hilaire on the publication of the Brazilian flora and introduced the first seeds of Jubaea chilensis in France.
He taught at Chaptal College as professor of zoology, but a neurological disease left him deaf. He became an assistant naturalist in 1854 and married in 1860. He entered the Academy of Sciences in 1863 where he succeeded Horace Benedict Alfred Moquin-Tandon.
He moved to Collioure in 1869 and created a private experimental garden there. He also made there the first local complete weather study, which lasted ten years.
In 1878 he was appointed director of the botanical garden of Villa Thuret of Antibes (now an INRA laboratory). He worked closely with Jacques Nicolas Ernest Germain de Saint-Pierre.
He was losing his sight. In spite of this he continued to run experiments on hybridization and the acclimation of plants for the production of new species. He studied heredity, and the flora of Brazil, and in 1860 he described twenty kinds of pumpkins.
