Potamon is a genus of freshwater or semiterrestrial crabs mainly found from Southern Europe through the Middle East, and as far east as north-western India.{{cite journal |journal=Raffles Bulletin of Zoology |title=On the genus "Potamon" and allies in Indochina (Crustacea: Decapoda: Brachyura: Potamidae) |author=Darren C.

Twenty species are currently recognised.{{cite journal |author=Ruth Jesse, Christoph D.
