Vitonus, also known as Vanne or Vaune, was a monk who served as the Bishop of Verdun during the early 6th century. Following the death of Bishop Firminus during the siege of Verdun by King Clovis I, the priest Euspicius was chosen to negotiate with the Frankish king. Although Euspicius declined the bishopric, he recommended his nephew, Vitonus, for the position. The king accepted this appointment, leading to Vitonus's leadership of the diocese until his death around 525.
