The gens Munatia was a plebeian family at Rome.
Members of this gens are first mentioned during the second century BC, but they did not obtain any of the higher offices of the Roman state until imperial times.
[3] The chief surnames of the Munatii under the Republic were Flaccus, Gratus, Plancus, and Rufus.
[3] Plancus, often written Plancius, denotes a person with flat feet.
[4][5] It was the cognomen of the most important family of the Munatii.
