Gnaeus Pompeius (consul 31 BC)
Gnaeus Pompeius was suffect consul in 31 BC, during the transitional period when Octavian, the future Augustus, was consolidating his powers as princeps.
A member of the plebeian gens Pompeia, he may have been one of the Pompeii Rufi, the son of Quintus Pompeius Rufus, and therefore the great-grandson of the dictator Sulla.
A senator, Gnaeus Pompeius was appointed suffect consul to replace Marcus Titius, and he held the office from October 1 through to December 31, 31 BC. Gnaeus Pompeius was also one of the Quindecimviri sacris faciundis, a priestly college, to which he belonged until his death in AD 14.
