In Greek mythology, the Heliadae (; Greek: Ἡλιάδαι) were the seven sons of Helios and Rhode and grandsons of Poseidon, brothers to Electryone. They were Ochimus, Cercaphus, Macareus or Macar, Actis, Tenages, Triopas, and Candalus (Nonnus adds Auges and Thrinax). They were expert astrologers and seafarers, and were the first to introduce sacrifices to Athena at Rhodes. They also drove the Telchines out of Rhodes.
