In Greek mythology, Electra (; Greek: Ἠλέκτρα 'amber') was one of the Pleiades, the seven daughters of Atlas and Pleione. She lived on the island of Samothrace. She had two sons, Dardanus and Iasion (or Eetion), by Zeus.

Electra was connected with the legend of the Palladium, the sacred statue, which became the talismanic protector of Troy. Electra, along with the rest of the Pleiades, were transformed into stars by Zeus. By some accounts, she was the one star among seven of the constellation not easily seen, because, since she could not bear to look upon the destruction of Troy, she hid her eyes, or turned away; or in her grief, she abandoned her sisters and became a comet.
