Gaius Fonteius Agrippa
- For other with this surname, see Agrippa (disambiguation).
was the name of two related people in Roman history:
- Gaius Fonteius Agrippa was one of the four accusers of Marcus Scribonius Libo in 16 AD. Agrippa profited financially from the accusation, as he was rewarded with a share of Libo's property after the man committed suicide. As a result of this prosecution, he was also made praetor in 17 AD. He is again mentioned in 19 AD, as offering his daughter for a vestal virgin, in competition with the daughter of Comicius Pollio, to replace one who had recently died. As Agrippa had been recently divorced, Pollio's daughter won the honor. Even still, as a consolation the emperor Tiberius gave Agrippa's daughter a million sestertii for her dowry.
- Gaius Fonteius Agrippa, probably the son of the preceding, was suffect consul in 58 AD. In 69 AD, he succeeded Aponius Saturninus as commander of the Roman province of Asia with proconsular power. He was recalled from that place by Vespasian, and placed over Moesia in 70 AD. He was shortly afterwards killed in battle by the Sarmatians. He was succeeded in Moesia by Rubrius Gallus
