Gaius Fufius Geminus

Gaius Fufius Geminus (died AD 29) was a Roman senator who lived during the Principate. He was ordinary consul in the year 29 with Lucius Rubellius Geminus as his colleague. Geminus was the son of Gaius Fufius Geminus.

A portion of his cursus honorum is known from an inscription recovered from Montefano in Italia, which recognized Geminus as the patron of the colony. Geminus began his senatorial career as a quaestor for the emperor Tiberius; after this he was the emperor's designate for the Republican office of plebeian tribune. Around this time, definitely before he acceded to the consulate, Geminus was admitted to the septemviri epulonum, one of the four most prestigious ancient Roman priesthoods.

According to Lactantius, Fufius Geminus was consul along with "Ruberius Geminus" the year that Jesus of Nazareth was crucified.

According to Tacitus, Geminus owed his successes in his senatorial career to the empress Livia, the mother of Tiberius. Tacitus also describes Geminus as "a man well-fitted to win the affection of a woman", and witty, and "accustomed to ridicule Tiberius with those bitter jests the powerful remember so long." Once Livia died, in the year of his consulate, Geminus was prosecuted for treason.
