The House of Gwynedd is the royal house of the Kingdom of Gwynedd, in medieval Wales. It is divided between the House of Cunedda and the House of Aberffraw, and lasted from c.401 to 1283.

The House of Gwynedd, divided between the earlier House of Cunedda, which lasted from c.401 to 825, was eventually replaced by the later House of Aberffraw, beginning in 844. The first is so named after Cunedda (386-460), the founding King of Gwynedd in late Roman Britain; and the second after Aberffraw, the old capital of Gwynedd.
This House was the first not being descended from the male line of Cunedda, as king Hywel ap Rhodri Molwynog was the last in the direct male line. Through inheritances from the great uncle of Merfyn the Oppressor, the line of Cunedda continued from the maternal side through the House of Aberffraw, and through the House of Dinefwr through Rhodri's son, king Cadell ap Rhodri.[1][2][3][4]
The Senior line of the House of Aberffraw descended from Prince Llywelyn the Great in patrilineal succession and became extinct on the death of Owain Lawgoch in 1378, while the House of Dinefwr was succeeded by its cadet branch, the House of Mathrafal.[5][6]
From the oldest documented genealogies of Welsh royal families, the House of Gwynedd claimed descent from king Beli Mawr as ancestor figure and head of Gwynedd through the line of Cunedda (b. 386), and appears in the Harleian genealogies and Jesus College MS 20 genealogies.[7][8][9] In Welsh legend, Beli Mawr is stated as the father of the historical Cassivellaunus, who led the Celtic defence against Julius Caesar and his invasion of Britain in 54 BC during the Gallic Wars, being featured in Commentarii de Bello Gallico.[10][11][12]
Under the laws of king Hywel Dda, which were adapted from the much earlier pagan Molmutine Laws, any son can inherit from his father. This refers even to illegitimate sons if they are acknowledged by their father. The throne cannot be inherited through the female line unless both her father and the ancestry of her spouse were royal. In many examples cousins were inter-married, which made the distinction somewhat academic.
The House of Aberffraw began with the accession of Rhodri Mawr to the throne of Gwynedd. His father Merfyn Frych ap Gwriad had seized the throne of Gwynedd on the death of the last of the old royal line Hywel ap Rhodri Molwynog. He was his maternal grandnephew via the former king's niece Esyllt verch Cynan ap Rhodri Molwynog.
