Eutropia (Greek: Εύτροπία; died after 325), a woman of Syrian origin,^[2] who was the wife of Emperor Maximian.^[3]

In the late 3rd century, she married Maximian, though the exact date of this marriage is unknown. By Maximian, she had two children: Maxentius, Roman emperor from 306 to 312, and Fausta, the wife of Constantine the Great and mother of emperors Constantine II, Constantius II, and Constans.

The parentage of Theodora, the wife of Constantius I, is disputed; most sources refer to her as Maximian’s stepdaughter, leading to the belief that she was born from Eutropia’s previous marriage to a man named Afranius Hannibalianus.^[4] Barnes, however, considered the few sources that refer to Theodora as Maximian’s daughter, rather than his stepdaughter, to be more reliable, and he suggested she was born from Maximian’s previous marriage, which would make Theodora Eutropia’s stepdaughter.^[5]
