Eutropia (died 350) was the daughter of Roman emperor Constantius Chlorus and Flavia Maximiana Theodora, and therefore half-sister of Constantine the Great. She was mother of the short-lived imperial pretender Nepotianus, and was probably killed alongside him by the rival usurper Magnentius in 350.
Eutropia (died after 325), a woman of Syrian origin, was the wife of Emperor Maximian. By Maximian, she had two children, a boy, Maxentius (c. 280–312), who was Western Roman Emperor from 306 to 312 and a girl, Fausta (c. 290), who was wife of Constantine the Great, and mother of six children by him, including the Augusti Constantine II, Constantius II and Constans.
