The gens Umbricia was a minor plebeian family at ancient Rome. Only a few members of this gens are mentioned by Roman writers, but they had achieved senatorial rank by the second century. The most famous of the Umbricii are probably the haruspex Gaius Umbricius Melior, who served the emperors of the middle first century, and Aulus Umbricius Scaurus, a merchant of Pompeii whose fish sauces were widely distributed. Quintus Umbricius Proculus was a second-century governor of Hispania Citerior. Many other Umbricii are known from inscriptions.
