Marcus Licinius Crassus Frugi (flourished 1st century BC & 1st century) was a Roman nobleman of consular rank who lived during the Roman Empire. Frugi’s mother was an unnamed Roman woman, while his father was consul and governor Marcus Licinius Crassus. Frugi’s adoptive paternal grandfather was consul and general Marcus Licinius Crassus. Crassus was the grandson of triumvir Marcus Licinius Crassus and the last known direct descendant of his grandfather. He had a sister called Licinia who married the consul, Lucius Calpurnius Piso whom their son, Gaius Calpurnius Piso who was a conspirator against the Roman emperor Nero.
Frugi served as a praetor and then later as a consul along with Lucius Calpurnius Piso in 27, under the reign of Roman emperor Tiberius. In the older historical sources, they record his consulship as in the year 29. Sometime after 44, he served as Roman Governor of Mauretania. During the reign of Roman emperor Claudius, Frugi had appeared to come into favor with the emperor. Claudius had successfully conquered Britain and had added Britain as a province to the Roman Empire. In 43, Claudius had held a triumph parade in Rome, in celebrating his victory of Britain. Frugi had attended Claudius’ triumph parade. Claudius on this occasion had except Frugi from wearing a purple-bordered toga and earned the same honor on a previous occasion. Frugi came dressed to the parade in a palm-embroidered tunic and rode a caparisoned charger. Little else is known on Frugi.
Frugi had married a noblewoman called Scribonia. She was of the highest birth and had descended from ancient, distinguished and politically influential blood. Scribonia was a direct descendant of Pompeia, the daughter of triumvir Pompey from his third marriage to Mucia Tertia.
