Saint Gervold (or Girowald, or Gerwald, or Gerbaud) is a monk, diplomat of Charlemagne, bishop of Evreux around 785, and abbot of Saint Wandrille from 787. He died in 806 or 807.
He was the uncle of Saint Ansegisus whom he tonsured and clerked around 795. Gervold then took him to the court of Charlemagne at Aix-la-Chapelle where he supervised the royal works.
