In Greek mythology, Hyperion (Greek: Ὑπεριων, "he who goes above" or "he who watches from above") was one of the Titans and a son of Uranus and Gaea. He was married to his sister, Theia, and fathered three children: Helios, Selene, and Eos. Hyperion was the Titan of heavenly light.

When Cronus was planning to overthrow his father, he persuaded Hyperion, Crius, Coeus, and Iapetus to help him. He had his brothers grab their father from the four pillars of the earth and hold him while Cronus castrated him. In this aspect, Hyperion presided over the east pillar.

After Zeus defeated Cronus, the Titans were imprisoned within Tartarus. Pindar and Aeschylus write that the Titans were eventually released from their prison.
