In Greek mythology, Porphyrion (Ancient Greek: Πορφυρίων) may refer to the following characters:
- Porphyrion, one of the Giants, offspring of Gaea, born from the blood that fell when Uranus (Sky) was castrated by their son Cronus.[1]
- Porphyrion, also known as Ornytion, a King of Corinth after succeeding his father, Sisyphus, the great trickster.[2] His mother was the Pleiad Merope, daughter of the Titan Atlas, and brother to Glaucus, Thersander and Almus.
- Porphyrion, son of Celeus and one of the Athenian sacrificial victims for the Minotaur.[3] He may be the brother of Hesione, another sacrificial victim granting that their father is only one and the same.
