The gens Titinia was a minor plebeian family at ancient Rome.
Members of this gens are mentioned as early as the time of the decemvirs, but only a few held any magistracies, and none of them ever attained the consulship.
In this instance, the name is likely derived from the nomen Titius, which in turn was formed from the praenomen Titus, and was reckoned a gentilicium of Sabine origin.
[2] The chief praenomina of the Titinii during the Republic were Marcus and Gaius.
The earliest Titinii mentioned in history also used Lucius and Sextus, while in a later period we find Publius, Quintus, and Gnaeus.
