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

[4] In the late 3rd century she married Maximian, though the exact date of this marriage is unknown.

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, since Theodora named one of her own sons Hannibalianus.

[5] Timothy Barnes, however, considers the few sources that refer to Theodora as Maximian's daughter to be more reliable, and suggests she was born from Maximian's previous marriage to a hypothetical daughter of Afranius, which would make Theodora Eutropia's stepdaughter instead.

[6] Julia Hillner agrees with Barnes that the stepdaughter sources are a result of political propaganda from the later Constantinian dynasty, but believes that his reading fails to explain why Theodora named one of her daughters Eutropia if her mother was an unknown Afrania instead of empress Eutropia.
