Augustin François César Prouvençal de Saint-Hilaire (4 October 1779 – 3 September 1853) was French botanist and traveller who was born and died in Orléans, France. A keen observer, he is credited with important discoveries in botany, notably the direction of the radicle in the embryo sac and the double point of attachment of certain ovules. He also described two families, the Paronychiae and the Tamariscinae, as well as many genera and species.
