The gens Titedia, also written as Titidia, or Titiedia, was an obscure plebeian family at ancient Rome. Hardly any members of this gens are mentioned by Roman writers, and only one, Titidius Labeo, held any of the higher magistracies of the Roman state; others are known from inscriptions.
The nomen Titedius belongs to a class of gentilicia formed using the suffix -idius to form nomina from cognomina ending in -idus. It resembles, and may be derived from the same root as the Titia gens.[1]
The main praenomina of the Titedii were Lucius and Gaius, which happen to be the two most common praenomina at all periods of Roman history. A few of the Titedii bore other names, including Gnaeus and Quintus.
