King Augvald (Ogvaldr) was a semi-legendary figure from the norse sagas. He reportedly lived at Karmøy, controlling the realm that included parts of what is today Hordaland and southern Norway. He may have lived between 500-650 AD.

He is considered as a great conquerer. He claimed to be a descendant of Ymir, the giant from whose body the world was created. He honored a holy cow, which he brought with him everywhere. He had two daughters, who followed him in every war. He, as well as the daughters and the cow were killed at a battle against a rival king of western Karmøy.

Augvald himself was the ancestor of West coast kings such as Hjør, Hjørleiv "the women lover" and Halv.

It is said that king Olav Tryggvason dug up two mounds at Karmøy, finding the bones of a man in the one and the bones of a cow in the other.
