Potamocypris smaragdina is a species of ostracod crustacean in the family Cyprididae, subfamily Cypridopsinae. It is known from both Europe and North America.[1]

Potamocypris smaragdina colonizes (fish)ponds, lakes and slow flowing streams. It is one of the most common freshwater ostracods in the United States.
