Jean Florimond Boudon de Saint-Amans (24 June 1748, Agen – 28 October 1831, Agen) was a French naturalist and antiquarian. He was the author of works involving agriculture, botany and antiquities.
At the age of 18 he joined the infantry regiment of Vermandois, of which he participated in journeys to the Caribbean. In 1773, he left the military, married a wealthy heiress, and moved back to his hometown of Agen. In 1794 he became a member of the board of agriculture to the Ministry of the Interior, and two years later was appointed professor of natural history at Ecole centrale de Lot-et-Garonne.
From 1800 until his death in 1831, he served a president of the General Council of Lot-et-Garonne.
