DIOPATRE was a Naiad Nymph of a spring of the river Sperkheios on Mount Othrys in Malis (northern Greece). She was loved by the god Poseidon, who transformed her sisters into poplar-trees in order to seduce her unhindered.
She was probably the same as Eidothea.

|A SON? (by Poseidon) (Antoninus Liberalis 22)
Antoninus Liberalis, Metamorphoses 22 (trans. Celoria) (Greek mythographer C2nd A.D.) :
"Kerambos (Cerabmus), son of Eusiros, who was the son of Poseidon and of Eidothea the Nymphe of Othreis, lived in the land of the Melians on the spurs of Mount Othrys . . . [Kerambos said that] the Nymphai [of Mount Othrys], were not descended from Zeus, but that Deino had given birth to them, with the River Sperkheios (Spercheus) was the father. He also said that Poseidon, for lust of one of them, Diopatre, had made her sisters put down roots and turned them into poplars until, satiated with his desires, he had returned them to their original shapes."
