Gaubald was an 8th-century Catholic prelate who served as the first official bishop of the Diocese of Regensburg in modern-day Germany. Appointed by Saint Boniface in 739, he also held the position of abbot at St. Emmeram's Abbey. During his leadership, he acted as a mitered abbot, managing both monastic and episcopal responsibilities within the region. He lived during a formative period for the local church hierarchy, following several wandering bishops who had previously operated in the area.
