Paul Charles Édouard Bertrand (10 July 1879, Loos-lez-Lille – 24 February 1944, Paris) was a French paleobotanist.

In 1910 he became a lecturer in paleontology and director of the Lille "coal museum".

From 1938 to 1944 (year of death), he served as chair of "Anatomie comparée des végétaux actuels et fossiles" at the Muséum national d'histoire naturelle in Paris.

[1][2] His work largely dealt with the comparative anatomy of fossil plants, comparative morphological investigations of living and fossil plants, and studies involving Carboniferous biostratigraphy.

He made significant contributions in his research on the structure of early ferns and fernlike plants.
