Félix Dujardin (April 5, 1802 - April 8, 1860) was a French biologist who was a professor at Toulouse and Rennes, and known for his study of protozoans and other invertebrates. He became a member of the French "Académie des sciences" later in life. Concerning his educational background, Dujardin was largely self-taught.

Dujardin is primarily known for his work with microscopic animal life, and in 1834 proposed that a new group of one-celled organisms be called "Rhizopoda"; meaning "root-foot. This name was later changed to Protozoa. He refuted naturalist Christian Gottfried Ehrenberg's (1795–1876) concept that microscopic organisms are "complete organisms" similar to higher animals .

In "Foraminifera", he noticed an apparently formless life substance that he named "sarcode"; which was later renamed protoplasm by Hugo von Mohl (1805-1872). Dujardin also did extensive research regarding other invertebrate groups including echinoderms, helminths and cnidarians.
