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.

[2] The only exception is the North African P. algeriense, which also is the only potamid of mainland Africa.

[1][3][4] These crabs are omnivores that have a broad ecological tolerance.

The adult Potaman reach up to 50 mm in size during their 10-12 year life span.

Many other taxa from Indochina, originally described as species of Potamon, are now placed in other genera, such as Himalayapotamon, Beccumon, Eosamon, and Takpotamon.
