In Greek mythology, Myrtoessa (Ancient Greek: Μυρτώεσσα) was an Arcadian nymph, specifically a Crinaeae, who together with other nymphs, Neda, Anthracia, Hagno and Anchirhoe, were nurses of the god Zeus.
She was depicted to carry water-pots with what is meant to be water coming down from her.
[1][2]A non marine mollusc called Myrtoessa hyas in the Hydrobiidae(mud snail) family, is named after the nymph.
