Arbogast or Arbogastes (died 8 September 394) was a Roman army officer of Frankish origin. He won distinction in the service of the emperor Gratian, and was subsequently entrusted by Theodosius I with the guardianship of the underage Valentinian II. The death of Valentinian in mysterious circumstances, and the rise of the controversial Eugenius, led to a civil war in which Arbogast perished.
