Gunther (1025/1030 – 23 July 1065) was a German nobleman and prelate of the Holy Roman Empire. He served as Chancellor of Italy from 1054 until 1057 and as Bishop of Bamberg from 1057 until his death. He was the leader of the Great German Pilgrimage of 1064–65, on which he died.
Gunther was a regular at the imperial court, a man of luxurious living and a patron of letters. He revived High German literature with his commissioning of the Ezzolied on the eve of his pilgrimage. He was buried in a rich silk, the so-called Gunthertuch, that he had acquired on the pilgrimage.
