Henry Wace was an English Anglican priest and ecclesiastical historian who served as Principal of King's College, London, from 1883 to 1897 and as Dean of Canterbury from 1903 to 1924. He is described in the Dictionary of National Biography as "an effective administrator, a Protestant churchman of deep scholarship, and a stout champion of the Reformation settlement".

The Dean of Canterbury is the head of the Chapter of the Cathedral of Christ Church, Canterbury, England. The current office of Dean originated after the English Reformation, although Deans had also existed before this time; its immediate precursor office was the prior of the cathedral-monastery.
