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.
