Prince de Soissons was a 5th-century prelate who served as the twelfth bishop of Soissons starting around 474. A member of a significant clerical family, he was the brother of Remigius of Reims and was either the uncle or father of Lupus of Soissons. His leadership spanned a transformative era in Gaul, witnessing the transition from Roman rule to the establishment of Frankish supremacy under Clovis I. Through his influence, he helped support the expansion of the Christian faith within the Frankish Empire.
