Monarchs of Rhos

Cuneglasus (fl. 540) was a prince of Rhos in Gwynedd, Wales, in the late 5th or early 6th century. He was castigated for various sins by Gildas in De Excidio Britanniae. The Welsh form Cynlas Goch is attested in several genealogies of the Rhos royal line. The two names are assumed to refer to the same ruler.
