M. Herennius M.f. Moneyer of the Roman Republic from 108 BC to 107 BC.
M. Herennius M.f. was one of the moneyers for the year 108-197 BC. He is presumably identical to the Consul for 93 BC.

Gens Herennia was a plebeian family at Rome. Members of this gens are first mentioned among the Italian nobility during the Samnite Wars, and they appear in the Roman Fasti beginning in 93 BC. In Imperial times they held a number of provincial offices and military commands. The empress Herennia Etruscilla was a descendant of this gens.

The extensive mercantile interests of the Herennii are attested by several authors, who describe the family's participation in the Sicilian and African trade, and especially their involvement in purchasing and exporting silphium, a medicinal herb of great value in antiquity, which grew only along a short stretch of the African coast, and defied all attempts to cultivate it.
