The Master of Zweder van Culemborg (sometimes referred to as Master Pancracius) was a North Netherlandish painter of illuminated manuscripts active in the area around Utrecht between 1420 and 1440. His namepiece is a canon page in a Missal depicting a bishop worshipping the crucified Christ. According to a coat of arms in the border of the painting, the religious is Zweder van Culemborg, nominated to the town's bishopric in 1423; he was, however, unable to take his position until 1425. In 1431 he left for the Council of Basle; he died there two years later.
