In Greek mythology, Phartis (Ancient Greek: Φαρτις) was one of the 50 Danaïdes, daughters of Danaus, king of Libya (and later of Argos).
Phartis' mother was an Ethiopian woman and thus, sister to Pirene, Dorium, Mnestra, Evippe, Anaxibia and Nelo.
On the orders of her father, Phartis married and eventually murdered her cousin–husband Eurydamas, son of King Aegyptus of Egypt by a Phoenician woman. Later on, because of the murder, she and her sisters — saved Hypermnestra — were punished in afterlife, being forced to carry a jug to fill a bathtub (pithos) without a bottom to wash their sins off. The water was always leaking that they would forever try to fill the tub.
