Hildebold (died 3 September 818) was the Bishop of Cologne from 787 until 795 and the first Archbishop of Cologne thereafter. A friend of Charlemagne, in 791 Hildebold was made the archchaplain and chancellor of the Imperial Council. At the request of Charlemagne, Pope Adrian I released Hildebold from the traditional episcopal requirement of residing in one's see. In 795, the pope raised Cologne to archiepiscopal status. The dioceses of Utrecht, Liège, Münster, Minden, Osnabrück, and Bremen were made suffragan. Hildebold began the construction of an extension of Cologne Cathedral that was only completed in 870, which in later times was called the Hildebold Cathedral.
