Nepotianus (died 465) was a general of theWestern Roman Empire.

Nepotianus married the sister ofMarcellinus, the semi-independent ruler of Dalmatia;Julius Nepos, lastWestern Roman Emperor, might have been their son and did at some point succeed Nepotianus as ruler of Dalmatia.

In theGothic War (457-458) he wascomes et magister utriusque militiae and together withAegidius, he commanded thearmy of the Western Emperor,Majorian. That same year Majorian started a military campaign to re-conquer Gaul; the army, reinforced by some barbarian mercenaries, dislodged theVisigoths ofTheodoric II fromArelate and obliged them to return to their condition offoederati. With the help of his renewedfoederati, Majorian entered in theRhone Valley, conquering its populations "some by arms and some by diplomacy".^[1] He defeated theBurgundians and besieged and conquered the city ofLugdunum: the rebel city was heavily fined, while theBagaudae were forced to join the Empire.^[2]

In 459, some envoys of Nepotianus and of the GothiccomesSunieric arrived inGallaecia to announce the victory of Majorian and the treaty between the Romans and the Visigoths.

In May 460, Nepotianus and Sunieric led some troops in a joint attack with Theodoric to theSuebi: Nepotianus moved to Gallaecia and attacked the Suebic army, defeating it nearLucus Augusti.

At the beginning of the 460s, Nepotianus was deposed by order of Theodoric II, maybe because he opposed the powerfulmagister militumRicimer, and was substituted byArborius. He died in 465.
