Flavia Maximiana Theodora (died before 337) was a Roman empress as the wife of Constantius Chlorus.

[3] Timothy Barnes challenges this view, arguing that all "stepdaughter sources" derive their information from the hypothetical 4th century Enmannsche Kaisergeschichte, which Barnes considers unreliable, while sources he considers to be more reliable refer to Theodora as Maximian's daughter, rather than his stepdaughter.

[5] In 293,[6] Theodora married Constantius Chlorus, the junior co-emperor of Maximian, after he had set aside Helena, mother of his son Constantine, to strengthen his political position.

After the death of her stepson Constantine, several of her male descendants were massacred, which Julian explicitly blamed Constantius II for.

[7] Constantine's successors proceeded to print coins of Theodora,[8] presumably in an attempt to distance themselves from the massacre.
