Quintus Fabius Julianus was a Roman senator active during the first half of the second century AD.
He was suffect consul for the nundinium of May to August 131 as the colleague of Lucius Fabius Gallus.
[2] In that article, Werner Eck and Andreas Pangerl admitted that he might be related to his colleague Gallus.
One was Quintus Fabius Iulianus Optatianus Lucius Fabius Geminus Cornelianus, a consul known from a lost inscription, who was the son of a Marcus who belonged to the tribe Galeria; Eck and Pangerl infer from these facts that Julianus came from Hispania Baetica.
[3] Another possible identification is Marcus Fabius Iulianus Heracleo Optatianus, whose membership in the Arval Brethren has been attested from 135 to 155.
