Varanes (floruit 393–410) was a politician and general of the Western and Eastern Roman Empires.
He probably followed Emperor Theodosius I to the West in 394, in his war against the usurper Eugenius.
He remained there, after Theodosius' death, under his son and successor Honorius.
The following year he was again in Constantinople, where he probably had received the office of Magister militum praesentalis; on this occasion, he suppressed a popular revolt caused by a food shortage.
That year Rome was besieged by the Visigoths of Alaric I, who would eventually sack the city; the usurper Priscus Attalus chose Tertullus as consul, but neither the Western Emperor Honorius nor the Eastern court of Theodosius II recognised him.
