Flavius Iulius Popilius Nepotianus Constantinus (d. 30 June, AD 350) was a member of the Constantinian dynasty, and short-lived usurper of the Roman Empire.

Nepotianus was the son of Eutropia, half-sister of Emperor Constantine I, and of Virius Nepotianus. On his mother's part, he was grandson of Emperor Constantius Chlorus and Flavia Maximiana Theodora.

After the revolt of Magnentius, Nepotianus proclaimed himself emperor and entered Rome with a band of gladiators on 3 June AD 350, which caused the urban prefect Titianus (or Anicius, or Anicetus), allied to Magnentius, to flee, after being defeated at the head of an undisciplined force of Roman citizens.

Magnentius quickly dealt with the situation by sending his trusted magister officiorum Marcellinus to Rome. Nepotianus was killed in the resulting struggle (30 June AD 350), his head put on a lance and brought around the city (Eutropius). In the following days, Eutropia was killed too, within the persecution of the supporters of Nepotianus, most of senators.
