Paullus Fabius Persicus (2/1 BCE - some time during the reign of Claudius) was the only son of Paullus Fabius Maximus and Marcia, a maternal cousin of Augustus (daughter of his aunt Atia and L. Marcius Philippus) and great-niece of Julius Caesar. As such, Persicus was a first-cousin-once-removed of Augustus and a great-great-nephew of Julius Caesar.
