Ansbald of Prüm was a 9th-century Benedictine abbot who led the monastery at Prüm from 860 until his death in 886. During his early years as a monk, he maintained a scholarly friendship with Lupus of Ferrières, assisting in the collection of Cicero's writings. As an influential leader, he secured various privileges for his abbey, including tax-exempt rights for a market and mint. He also served as a key supporter of King Louis the German within the region of Lotharingia.
