Léon Diguet (25 July 1859, Le Havre – 31 August 1926, Paris) was a French biologist and geologist.

He studied science at the Muséum national d'histoire naturelle in Paris, where he was influenced by scientists that included, biologist Jean Louis Armand de Quatrefages de Bréau, zoologist Alphonse Milne-Edwards and anthropologist Ernest Hamy.[1] From 1889 to 1892 he was employed as a chemist at a mining installation in Santa Rosalia, Baja California — and in the meantime, collected natural history specimens for the natural history museum in Paris. Afterwards, from 1893 to 1914, he made six more trips to Mexico as an explorer and collector:

As a naturalist in Mexico, he amassed an eclectic collection of insects, cacti, orchids, minerals, crustaceans, et al. Also, he performed archaeological studies in the Mixtec-Zapotec region and at Ixtlán del Río, conducted historical research of cochineal, studied the Huichol language, analyzed the different types of agave and investigated the properties of jojoba. On his journeys, he took many photographs of the country. the negatives later being housed at the Musée de l'Homme in Paris.[2]

The genus Diguetia bears his name,[3] and his name is also associated with numerous zoological and botanical species, two examples being: Sceloporus digueti (synonym Sceloporus orcutti, the granite spiny lizard) and Ferrocactus diguetii (a species of barrel cactus).[4][5]
