Jean Vincent Félix Lamouroux (3 May 1779 – 26 March 1825) was a French biologist and naturalist, noted for his seminal work with algae.

In 1807, Lamouroux was appointed to the French Academy of Sciences and in 1808 he became an assistant professor of natural history at the University of Caen, rising to full professorship by 1811.

He joined the Linnean Society of Calvados and contributed to its publications, collaborating with his friend Jean Baptiste Bory de Saint-Vincent.

In 1813, Dawson Turner adopted Lamouroux's classification system for algae, providing it with international credence.

[6] In 1818, botanist Carl Sigismund Kunth described a genus of plants from Mexico and Central America, (in the family Orobanchaceae), as Lamourouxia in his honour.
