Adrien Blanchet (March 8, 1866 - December 27, 1957) was a French scholar of ancient Rome and Gaul. He studied at the Ecole des Hautes Études and the Ecole du Louvre, taking courses with many of the leading French archaeologists of the time. He worked for many years at the Cabinet des médailles of the Bibliothèque nationale de France and was a leading expert on the coinage of the ancient world, serving as the Secretary and then Director of the Revue numismatique. He was elected a member of the Académie des Inscriptions et Belles-Lettres in 1919. His knowledge of the ancient world expanded into other fields as well, such as research on aqueducts. He oversaw the multipart atlas series Carte archéologique de la Gaule romaine in the late 1920s and early 1930s.
