WIGHARD, WIGHEARD, or VIGHARD (d. 664), archbishop-elect of Canterbury, was a Kentish priest and one of Deusdedit's clergy. He was nominated to the archbishopric with the assent of the English church by the kings Oswy and Egbert, and was sent, bearing gold and silver vessels, to Rome for consecration. He died of the plague in Rome in 664, before his consecration. He is described as very learned in ecclesiastical discipline.
