Basilina (died 332) was the wife of Julius Constantius and the mother of Roman Emperor Julian, who in her honour gave the name Basilinopolis to a city in Bithynia (modern Pazarköy near Gemlik, in Turkey).
Basilina was born of Greek origin, the daughter of Caeionius Iulianus Camenius or, more likely, of Julius Julianus, she was educated by Mardonius, a eunuch who grew up in the house of her father. She became the second wife of Julius Constantius, whom she gave Julian; Basilina died a few months after childbirth. Her sister was the mother of Procopius.
