Wiliesind was a bishop of Pamplona (floruit 848–67). His episcopate falls in a very obscure period in Pamplonan history. His predecessor, Opilano (floruit 829), is the first bishop mentioned in source after 693, and no successor of his is known before Jimeno in the 880s. Wiliesind's name is Gothic in origin, although the diocese of Pamplona was predominantly Basque at the time. It probably indicates that Pamplona still looked at Toledo as its spiritual guide, rather than across the Pyrenees.
