Johann, or Jean, Hermann (December 31, 1738 in Barr, Alsace - October 4, 1800 in Strasbourg) was a French physician and naturalist. He was professor of medicine at the University of Strasbourg. He was the author of Tabula affinitatum animalium (1783) and Observationes zoologicae quibus novae complures, published posthumously in 1804. His zoological collection was bought by the city of Strasbourg in 1804 and served as the base for the Strasbourg zoological Museum.
Hermann's name survives most famously through Hermann's Tortoise.
