Gaius Oppius Sabinus Julius Nepos Manius Vibius Sollemnis Severus was a Roman senator, who was active during the reign of Hadrian.
After completing his term as praetor, Oppius Sabinus was selected as the legatus proconsulis or assistant to the governor of Hispania Baetica, a post commonly held for one year.
He returned to Rome, where he was appointed curator of a number of roads: the viae Clodia, Annia, Cassia, Cimina, tria Trajanarum, and Amerina.
Then he accepted a commission as legatus legionis or commander of the Legio XI Claudia, then stationed at Durostorum (Silistra) on the Danube, which kept him from Rome for three years.
However, the primary objection to this surmise is that were the younger Oppius Sabinus the son of the consul of 84, he would have been considered a nobiles, or member of the Senatorial class, and not in need of being adlected into the Senate.
As for the dates of his career, little improvement can be made on the conclusion originally offered by Attilio Degrassi and since accepted by Géza Alföldy that Oppius Sabinus acceded to the consulate between the years 130 and 138.
