Balderic (Oldenzaal, 897 – Utrecht, 27 December 975) was Bishop of Utrecht from 918 to 975.
Balderic descended from the Counts of Hainaut. He was a cousin of Duke Gilbert of Lorraine and the uncle of Bishop Balderic of Liège. He was the son of Count Ricfried in the Betuwe, who expelled the Vikings from Utrecht, after which Balderic, who like his immediate predecessors had resided in Deventer, was able to move the bishopric back to Utrecht.
In Utrecht, Balderic repaired the forerunner of the Cathedral of Utrecht, St. Martin, and rebuilt the St. Salvator Church, which had been destroyed by the Normans, as well as the convent school that was attached to the Cathedral Chapter. Under his influence, Utrecht became the most important city in the northern Netherlands and he expanded the power of the local diocese so that it could maintain itself between the surrounding counties. This was achieved through his support of the German king, who granted him possessions in return.
Balderic was very successful in this policy: in 923 he formed close relations with the German King Henry I (919-936), who in return entrusted Balderic with the education of his four-year-old son Bruno, future archbishop of Cologne.
Because of this, Balderic also kept close contact with Henry's other son and successor, King Otto I (936-973). He belonged to the Lorrainian lords that sided with Otto in his struggle with his sons in 953. In exchange, Otto granted Balderic the right of coinage in Utrecht, as well as the trade settlement Muiden including the important toll. Furthermore, he acquired hunting rights in Drenthe, and several possessions in the Gau (country subdivision) Lek and IJssel.
