Hariulfus  Hariulf (Latin: "Hariulfus") was a Burgundian prince during the 4th century. An inscription records one "Hariulfus", son of "Hanhavaldus", of the royal family of the Burgundians ("regalis gentis Burgundionum"), who was already a "protector domesticus" when he died at the age of twenty in the imperial court in "Augusta Treverorum" ("Germania Superior"), probably under the Roman Emperor Valentinian I (reign 364-375 AD):  This inscription was found in 1877 at Trier, Germany.
