Quintus Caecilius Metellus Numidicus (ca 160 BC – 91 BC) was the leader of the conservative faction of the Roman Senate and a bitter enemy of Gaius Marius. He served as consul for 109 BC, and was the chief commander in the Jugurthine War in Numidia until Marius displaced him. 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.
