'''Cadfan ap Iago''' (c. 569 – c. 625) was [[List of rulers of Gwynedd|King of Gwynedd]] (reigned c. 616 – c. 625). Little is known of the history of Gwynedd from this period, and information about Cadfan and his reign is minimal.<ref>{{Cite DNB |wstitle=Cadvan |author-first=Thomas Frederick |author-last=Tout |authorlink=Thomas Frederick Tout |page=190}}</ref>

The historical person is known only from his appearance in royal genealogies, from his grant to [[Beuno|Saint Beuno]] for the monastery at [[Clynnog Fawr]], and from his inscribed gravestone in [[St Cadwaladr's Church, Llangadwaladr]].

Cadfan was the son and successor of King [[Iago ap Beli]] and is listed in the royal genealogies of the [[Harleian genealogies]] and in [[Genealogies from Jesus College MS 20]].{{sfn|Phillimore|1888|pp=169–170}}{{efn|the pedigree is given as: ''... map Rotri map mermin map etthil merch cinnan map rotri map Intguaul map Catgualart map Catgollaun map Catman map Iacob map Beli map Run ...'', and from there back to [[Cunedda]] and his ancestors.}}{{sfn|Phillimore|1887|pp=87}}{{efn|Phillimore, The pedigree is given as ''...

However, there is no evidence that Gwynedd had any part in the battle,<ref>{{Harvcolnb|Lloyd|1911|pp=181}}, ''A History of Wales'', Vol. I.</ref> so Cadfan's accession at that time appears to be no more than coincidence.

Cadfan was succeeded as king by his son, [[Cadwallon ap Cadfan]].
