Basilina (Βασιλίνα; died 332/333) was the wife of Julius Constantius and the mother of the Roman emperor Julian (r. 361–363) who in her honour gave the name Basilinopolis to a city in Bithynia (modern Pazarköy near Gemlik, in Turkey).
Basilina was of Greek descent born in Asia Minor. She was either the daughter of Caeionius Iulianus Camenius,[1] or more likely of Julius Julianus, and received a classical education (i.e., Homer and Hesiod) from Mardonius, a eunuch who grew up in the house of her father.[2] She had a sister who became the mother of Procopius.[3] She was a relative of Bishop Eusebius of Nicomedia, her son's tutor.
She became the second wife of Julius Constantius, whom she gave Julian; Basilina died a few months after childbirth.[2] A Christian, Basilina initially favoured the Arians, but gave her lands as an inheritance to the church of Ephesus.[4]
