The gens Nonia was a plebeian family at ancient Rome. Its members first appear in history toward the end of the Republic. The first of the Nonii to obtain the consulship was Lucius Nonius Asprenas in 36 BC. From then until the end of the fourth century, they regularly held the highest offices of the Roman state.[1]
