Regino of Prüm (Latin: Regino Prumiensis, German: Regino von Prüm; died 915) was a Benedictine churchman, who served as abbot of Prüm (892–99) and later of Saint Martin's at Trier, and chronicler, whose Chronicon is an important source for late Carolingian history.
According to the statements of a later era, Regino was the son of noble parents and was born at the stronghold of Altrip on the Rhine near Speyer at an unknown date. From his election as abbot and from his writings, it is evident that he had entered the Benedictine Order, probably at Prüm itself, and that he had been a diligent student. The rich and celebrated Imperial Abbey of Prüm suffered greatly during the 9th century from the marauding incursions of the Norsemen. It had been twice seized and ravaged, in 882 AD and 892 AD. After its second devastation by the Danes, the abbot Farabert resigned his office and Regino was elected his successor in 892 AD. His labours for the restoration of the devastated abbey were hampered by the struggle between contending parties in Lorraine.
