The gens Viridia was an obscure plebeian family at ancient Rome.
Members of this gens are known only from inscriptions, evidently dating to imperial times.
The nomen Viridius seems to be derived from the Latin viridis, green.
[1] Since one of the Viridii left a libationary inscription at Aquae Sulis in Britain, some connection with the obscure British deity Viridios has been suggested, but other Viridii are known from different parts of the Empire.
Two cognomina appear in extant inscriptions: Firmus, a common surname that translates as "firm, strong, hardy",[3] and Tertulla, a diminutive of Tertia, an old feminine praenomen, which was widely used as a surname throughout Roman history.
