Quintus Volusius Flaccus Cornelianus was a Roman Senator who lived during the 2nd century. He was ordinary consul in 174 as the colleague of Lucius Aurelius Gallus.^[1]

Little is known on his origins and life. Cornelianus was a member of the gens Volusia. He may have been a descendant of Quintus Volusius Saturninus, consul of 92.^[2]

The name of Cornelianus is mentioned in a Roman papyrus written between 193 and 197.^[3] The papyrus, written in Latin and Greek, contains a list of soldiers in some type of military unit, perhaps cavalrymen. It was probably later reused as an envelope for a letter or a small object.^[3]
