René Jeannel (23 March 1879 – 20 February 1965) was a French entomologist. He was director of the Muséum national d'histoire naturelle from 1945-1951. Jeanell's most important work was on the insect fauna of caves in the Pyrenees, France and in the Carpathians, Romania. He also worked in Africa. Jeannel specialised in Leiodidae (then Anisotomidae) but authored a large number of papers and works on other Coleoptera. He was a member of the Romanian Academy.
