Gnaeus Pompeius (consul 31 BC)

Gnaeus Pompeius (Rufus) (died AD 14) 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.
