Matienus - Monetalis of Res Publica Romana from 169 BC to 158 BC
Matienus was one of the moneyers for the years 179-170 BC. He is not otherwise known.

Gens Matiena was a plebeian family at Rome. Members of this gens first appear in history in the time of the Second Punic War. Chase classifies the nomen Matienus as part of a group of Latin gentilicia that appear to be derived from other nomina, although the ultimate origin of the name is not apparent.
