Quintus Caecilius Metellus Numidicus () was an ancient Roman statesman and general. He was a leader of the Optimates, the conservative faction of the Roman Senate. He was a bitter political opponent of Gaius Marius. He was consul in 109 BC; in that capacity he commanded the Roman forces in Africa during the Jugurthine War. In 107 BC, he was displaced from his command by Marius. On his return he was granted a triumph and the agnomen Numidicus. He later became a censor, entering into exile in opposition to Marius. Metellus Numidicus enjoyed a reputation for integrity in an era when Roman politics was increasingly corrupt.

Youth and cursus honorum

The son of Lucius Caecilius Metellus Calvus, in his youth he was sent to Athens where he studied under Carneades, celebrated philosopher and great master of oratory. He returned ostensibly cultured and with brilliant oratorical skills.

He was quaestor in 126 BC, tribune of the plebs in 121 BC, aedile in 118 BC, praetor in 115 BC, Governor of Sicily in 114 BC, and elected consul for 109 BC. The war dragged out into a long and seemingly endless campaign as the Romans tried to inflict a decisive defeat on Jugurtha. Metellus gained just one important victory over Jugurtha at the Battle of the Muthul.

Exile and later life

The tribune Saturninus proposed a law to exile Metellus Numidicus. Rather than face a confrontation between Saturninus' and his own supporters, who were prepared to defend him by force, Metellus departed into exile voluntarily, spending a year in Rhodes. He was accompanied into exile by a rhetorician, Lucius Aelius Praeconinus or Stilo, and pursued his study of philosophy while in Rhodes.
