• Pisidice, a Thessalian princess as the daughter of King Aeolus of Aeolia and Enarete, daughter of Deimachus. She was the sister of Salmoneus, Athamas, Sisyphus, Cretheus, Perieres, Deioneus, Magnes, Calyce, Canace, Alcyone and Perimede. Peisidice was the mother of Antiphus and Actor by Myrmidon.^[1] She may also be the mother of Myrmidon's other children: Erysichthon,^[2] Dioplethes,^[3] Hiscilla^[4] and Eupolemeia.^[5]
• Pisidice, an alternate name for Demonice, mother of Thestius by Ares.^[6]
• Pisidice, a princess of Iolcus as the daughter of Pelias, who, together with her sisters, killed their father, as Medea tricked them into believing this was needed to rejuvenate him.^[7]

• Pisidice, a princess of Methymna, who fell in love with Achilles as he besieged her city, and promised to put Methymna into his possession if he would marry her. He agreed to her terms but, as soon as the city was his, he ordered that she be stoned to death as a traitor.^[12][13]
• Pisidice, a queen of Haliartus as wife of King Copreus.^[14] She was of royal descent as well as the daughter of King Leucon of Boeotia. By her husband, Pisidice became the mother of Hippoclus^[14] and Argynnos, who was loved by Agamemnon and drowned in River Cephissus.^[15]
