The gens Quartia was an obscure plebeian family at ancient Rome. No members of this gens appear in history, but several are known from inscriptions.
The nomen Quartius is a patronymic surname, derived from the cognomen Quartus, fourth. There may at one time have been a praenomen Quartus, but it was not in general use in historical times, except in the feminine form, Quarta, which was regularly used as both a praenomen and cognomen. [1]
