Vortiporius or Vortipor (, Middle Welsh Gwrdeber or Gwerthefyr) was a king of Dyfed in the early to mid-6th century. He ruled over an area approximately corresponding to modern Pembrokeshire, Wales. Records from this era are scant, and virtually nothing is known of him or his kingdom. The only contemporary information about Vortiporius comes from the Welsh ecclesiastic Gildas, in a highly allegorical condemnation from his De Excidio et Conquestu Britanniae (). At the time the work was written (c. 540), Gildas says that Vortiporius was king of Dyfed, that he was grey with age, that his wife had died, and that he had at least one daughter. As a legendary king in Geoffrey of Monmouth's 12th-century treatment of the Matter of Britain, the Historia Regum Britanniae, Vortiporius was the successor of Aurelius Conanus and was succeeded by Malgo. He is not mentioned in the 9th-century Historia Brittonum attributed to Nennius. Vortiporius appears in the Irish genealogy given in the 8th-century work The Expulsion of the Déisi, in which his name is given as Gartbuir. The pedigree given in the Harley MS 5389, written c. 1100, is nearly identical, with his name given as Guortepir. In the Jesus College MS. 20, he is called Gwrdeber. The genealogy in Expulsion says he was a descendant of Eochaid Allmuir ( [literally (from) Overseas]), who is said to have led a sept of the Déisi in their settlement of Dyfed c. 270. A memorial stone was discovered in 1895 near the church of Castell Dwyran in Carmarthenshire bearing a Christian cross and with inscriptions in both Latin and in ogham. Dedicated to Voteporigis in the Latin inscription and Votegorigas in ogham, it was immediately assumed that this referred to Vortiporius. However, this assumption is refuted by modern linguistic analysis, which notes that the missing 'r' in the first syllable of 'Voteporigis'/'Votegorigas' is significant, and so the stone must be dedicated to a different person. Gildas In his De Excidio et Conquestu Britanniae (), written c. 540, Gildas makes an allegorical condemnation of 5 British kings by likening them to the beasts of the Christian Apocalypse as expressed in the biblical Book of Revelation, 13-2: the lion, leopard, bear, and dragon. In the course of his condemnations, Gildas makes passing reference to the other beasts mentioned in the Apocalypse, such as the eagle, serpent, calf, and wolf. Vortiporius is called "the spotted leopard" and
