  Jacques Clarion (12 October 1779 in Saint-Pons, Alpes-de-Haute-Provence – 28 September 1844 in Garches) was a French physician, pharmacist and botanist.
  
  In his youth, he served as an apprentice-pharmacist in the town of Seyne, while in the meantime studying plants native to the Alps. Up until 1799, he performed military service as a pharmacist third-class in Italy. He later studied medicine in Paris, and in 1805 began work as a pharmacist in the service of Emperor Napoleon. In this role, he served as director of the pharmacy at the Palace Saint-Cloud, a position he maintained during the reigns of Louis XVIII and Charles X.
  
  In 1819 he became an assistant professor at the Ecole de Pharmacie de Paris, and in 1825 a professor of botany. From 1822 to 1830 he was a member of the Académie de Médecine.
  
  In 1812, the botanical genus Clarionea (Lagasca ex A. P. de Candolle, 1812) was named in his honor.
