Jean Louis Marie Poiret (11 June 1755 in Saint-Quentin – 7 April 1834 in Paris) was a French clergyman, botanist and explorer.
From 1785 to 1786 he was sent by Louis XVI to Algeria to study the flora.
After the French Revolution he became a professor of natural history at the Écoles Centrale of Aisne.
The genus Poiretia of the legume family Fabaceae was named after him in 1807 by Étienne Pierre Ventenat.
