Hywel ap Ieuaf

Hywel ap Ieuaf (died 985) was a King of Gwynedd in North West Wales from 979 to 985.

Hywel was the son of Ieuaf who had ruled Gwynedd jointly with his brother Iago ab Idwal until 969.

Later chroniclers made the kings into eight, all plying the oars of Edgar's state barge on the River Dee.

In this raid, Hywel was assisted by English troops, possibly provided by Ælfhere, Earl of Mercia.

Hywel was left as sole ruler of Gwynedd, but apparently did not set his father free, since according to John Edward Lloyd, Ieuaf remained in captivity until 988.
