Marcus Asinius Agrippa was a Roman senator, who was active during the Principate.
He was consul in AD 25 as the colleague of first Cossus Cornelius Lentulus, then of Gaius Petronius.
[2] According to Tacitus, Agrippa was descended from a family more illustrious than ancient, and did not disgrace it by his mode of life, although he mentions no specifics.
[3] Agrippa was the half-brother of Drusus Julius Caesar, the natural son of the Emperor Tiberius.
