The gens Sergia (or the Sergii), was a famous patrician family in ancient Rome, of which Lucius Sergius Catilina was a member.
The Sergii were one of the oldest patrician families in Rome. Although they were of consular heritage, the Sergii were by the time of the conspiracy of Catiline in the first century BCE declining in both social and financial fortunes.
Virgil later gave the family an ancestor, Sergestus, who had come with Aeneas to Italy, presumably because they were notably ancient; but they had not been prominent for centuries, Sergestusque, domus tenet a quo Sergia nomen.
The last Sergius to be consul had been Gnaeus Sergius Fidenas Coxo in 380 BC.
