Potamides (; ) were a type of water nymph of Greco-Roman mythology. They were assigned to a class of nymphs of fresh water known as naiads and as such belonged to a category that presided over rivers and streams. Origin and abode Potamides were identified by the names associated with the rivers of their origin such as the Anigrides, Ismenides, Amnisiades, the Pactolides from the Pactolus river, and the Acheloides from the Achelous river. However they had their individual names and also sometimes could be distinguished by the name of the country in which they inhabited. The rivers were the domains of potamides as well as of the nymphs Fluviales. Every creek had its potamide, who as local divinities, and like all the naiads, were daughters of the gods of rivers, also called Potamoi.

Potamides showed themselves very favorably inclined to young girls and gently removed the freckles from all who bathed in their streams. On the other hand, they had an aggressive behavior directed at young men coming near their watery territories, whom they dragged down to their abodes. It was believed by the ancients that they carried water for their river parents, as was quoted: "In the lonely hour of noon the naiads sat with their water-pitcher at the spring-sending forth from it the warbling brook." Regarded as a profuse class of minor female divinities, they were believed to inspire those that drank of their waters. Thus potamides, and nymphs in general, were conceived to be endowed with oracular power, to inspire men with the same prophetic gift, and to bestow upon them the natural talent of poetry. Hence, as water is a necessity to
