Marcus Caecilius Metellus was a name used by some men of the gens Caecilia during the Roman Republic, including:
Marcus Caecilius Metellus, a praetor in 206 BC.
Marcus Caecilius Metellus, a consul in 115 BC.
Marcus Caecilius Metellus, a praetor in 69 BC who presided over the quaestio de repetundis, a standing tribunal of senatorial iudices (juror-judges) for investigating and deciding cases of extortion. Verres, who was prosecuted by Cicero, had hoped to have his trial postponed until Caecilius Metellus was presiding over the court.
Marcus was less frequent as a praenomen for the Caecilii Metelli than Lucius or especially Quintus.
