The gens Lucilia was a plebeian family at ancient Rome. The most famous member of this gens was the poet Gaius Lucilius, who flourished during the latter part of the second century BC.^[1] Although many Lucilii appear in Roman history, the only one known to have obtained any of the higher offices of the Roman state was Lucilius Longus, consul suffectus in AD 7.^[2]

The nomen Lucilius is a patronymic surname, derived from the common Latin praenomen Lucius.^[3] The satirist Lucilius is said to have come from Suessa Aurunca, an ancient town of the Aurunci, where a Latin colony was established in 313 BC.^[4]

In the time of the Republic, the surnames of the Lucilii were Balbus and Bassus, the former originally referring to one who stammers, and the latter referring to someone stout or sturdy. Later, in imperial times, we find Capito, given to one with a large or prominent head, and Longus, "tall". Rufus, commonly given to someone with red hair, appears on coins of the Lucilii, but the cognomen is not mentioned by any ancient writer. A number of the Lucilii are mentioned without a surname.^[1][5]
