Jean Baptiste Alphonse Déchauffour de Boisduval (24 June 1799 – 30 December 1879) was a French lepidopterist, botanist, and physician.

While best known abroad for his work in entomology, he started his career in botany, collecting a great number of French plant specimens and writing broadly on the topic throughout his career, including the textbook Flores française in 1828.

[1] Early in his career, he was interested in Coleoptera and allied himself with both Jean Théodore Lacordaire and Pierre André Latreille.

He was the curator of the Pierre Françoise Marie Auguste Dejean collection in Paris and described many species of beetles, as well as butterflies and moths, resulting from the voyages of the Astrolabe, the expedition ship of Jean-François de Galaup, comte de La Pérouse and the Coquille, that of Louis Isidore Duperrey.

[1] His brother was Adolphe-Armand d'Echauffour de Boisduval (September 26, 1801 – March 1, 1842), a doctor, naturalist, and health officer in their native Ticheville.
