List of kings of Dumnonia
A list of Dumnonian kings is one of the hardest of the major Dark Age kingdoms to accurately compile, as it is confused by Arthurian legend, complicated by strong associations with the kings of Wales and Brittany, and obscured by the Saxon advance. Therefore, this list should be treated with caution.
The original Celtic chiefs of the Dumnonii ruled in the south-west until faced with the Roman arrival into their territory in c.AD 55 when the Romans established a legionary fortress at Isca Dumnoniorum (modern Exeter). Although subjugated by c.AD 78, the civitas Dumnoniorum was one of the regions of Roman Britain least affected by Roman influence. Known as Caer Uisc, Exeter was inhabited by Dumnonian Britons up until c.936 when King Athelstan expelled them. Several other royal residences may also have served the kings of Dumnonia or Cornwall, including Tintagel, and Cadbury Castle.

Susan Pearce views the only native 4th to 7th century Dumnonian rulers to be known to history as:
- Constantine; Welsh Custennin Gorneu mentioned in De Excidio et Conquestu Britanniae
- Geraint; Welsh Geraint fab Erbin
By the end of the 8th century, Dumnonia was much reduced in size by the advance of the West Saxons and the remaining territory became a rump state in Cornwall. The generally accepted date for this transition is around 800.
- King Mark – of Tristan and Iseult fame, probably ruled in the late 5th century. According to Cornish folklore, he held court at Tintagel.
- King Salomon – father of Saint Cybi, probably ruled after Mark; not to be confused with Salomon, King of Brittany.
- Dungarth – was recorded by the Annales Cambriae as having drowned in 876. The Annales refer to him as "rex Cerniu", King of Cornwall.
- In records open to interpretation
- Ricatus (fl. c.900s) is mentioned on a memorial stone; he may have ruled a more localised region.
- Huwal of the West Welsh (c.910–c.926), about whom there has been controversy since the 19th century. He only appears in the Anglo-Saxon Chronicle entry for 927, accepting King Athelstan of Wessex as his overlord. 'West Wales' was an old term for Dumnonia or Cornwall, but may also refer to present day West Wales, then generally known as Deheubarth, where Hywel Dda was king.
- The Book of Baglan
- Ithel Eiddyn ap Donyarth (Ithel the Rock) (c.710–c.715)
- Dyfnwal Boifunall ap Ithel (Dyfnwal of Boifunall) (fl. c.730s)
- Cawrdolli ap Dyfnwal (fl. c.750s)
- Oswallt ap Cawrdolli (fl. c.770s)
- Hernam ap Oswallt (fl. c.790s)
- Hopkin ap Hernam (fl. c.810s)
- Mordaf ap Hopkin (fl. c.830s)
- Fferferdyn ap Mordaf (fl. c.850s)
- Donyarth (c.865–c.876)
- Eluid ap Fferferdyn (fl. c.880s)
- Alanorus ap Eluid (fl. c.890s)
- According to William of Worcester, writing in the 15th century, Cadoc, described as the last survivor of the Cornish royal line at the time of the Norman Conquest in 1066, was appointed Earl of Cornwall by William I of England.
- In the De Gestis Herewardi Saxonis written in the 12th century it is recorded that Hereward the Wake took refuge in Cornwall in the 11th century at the court of the Cornish Prince or King Alef.
If he is not to be identified with Hywel Dda of Deheubarth, the singularly recorded Huwal could have been the last native king. Some of the later supposed rulers listed below are given the title 'Earl of Cornwall', although in two cases may have been recognized as rebel kings (Conan in 934 and Cadoc in 1100).

- Alured ap Veffyne (fl. c.1000s) as 'Duke of Cornwall and Wessex'
