The gens Abudia was an obscure plebeian family at ancient Rome. This gens flourished during imperial times, and none of its members held any of the higher magistracies of the Roman state. Only Abudius Ruso, who had been aedile under Tiberius, is mentioned in history, but other Abudii are known from inscriptions.

The chief praenomina of the Abudii were Marcus, Publius, and Titus, each of which was very common throughout Roman history. Epigraphy also supplies examples of Gnaeus, Lucius, and Quintus.

This list includes abbreviated praenomina. For an explanation of this practice, see filiation.

• Abudius Ruso, a former aedile, had commanded a legion under Gnaeus Cornelius Lentulus Gaetulicus in Germania Superior. He was one of the delatores who accused Lentulus, but when the accusation failed, Abudius was instead condemned and exiled from Rome. Abudius' motivation for denouncing Lentulus may have been blackmail. The nature of his accusation is also unclear, but it might have been based on the betrothal of Lentulus' daughter to the son of Sejanus.^[1][2]
