In Greek mythology, Pandora (Ancient Greek: Πανδώρα, derived from πᾶς "all" and δῶρον "gift", thus "all-gifted" or "all-giving") was a daughter of King Deucalion and Pyrrha who was named after her maternal grandmother, the more famous Pandora.
According to the Hesiodic Catalogue of Women (fr. 5), she was the mother of Graecus by the god Zeus.
Her brother was Hellen.
