Maximilien Chaudoir, or Maximilien, baron de Chaudoir, (12 September 1816, Ivnytsia , near Zhytomyr – 6 May 1881, Amélie-les-Bains) was a Ukrainian entomologist. He was a specialist in Coleoptera and in particular the Carabidae. His Cicindelidae are conserved by the Muséum national d'histoire naturelle in Paris. His Carabidae were acquired by Charles Oberthür (1845–1924), then given to the same museum. He wrote Mémoire sur la famille des Carabiques, 6 volumes commencing 1848.[1]
