King Bridei III (or Bridei map Beli; O.Ir.: Bruide mac Bili) (616/628?-693) was king of Fortriu and overking of the Picts between 671 and his death in 693.Bridei may have been born as early as 616, but no later than the year 628. He was the son of Beli, King of Alt Clut. His claim to the Fortrean Kingship came through his paternal grandfather, King Nechtan of the Picts. Nennius' Historia Brittonum tells us that Bridei was King Ecgfrith's fratruelis, i.e. maternal first cousin. Bridei's mother was probably a daughter of King Edwin of Deira.
