Iago ab Idwal ap Meurig was a Prince of Gwynedd. On the death of Llywelyn ap Seisyll in 1023, the rule of Gwynedd returned to the ancient dynasty with the accession of Iago, who was a great-grandson of Idwal Foel.
Very little is known about the reign of Iago. He was killed by his own men in 1039 and replaced by Llywelyn ap Seisyll's son, Gruffydd ap Llywelyn. Iago's grandson Gruffydd ap Cynan later won the throne of Gwynedd, and because his father, Cynan ap Iago, was little known in Wales, Gruffydd was styled "grandson of Iago" rather than the usual "son of Cynan".
