Lucius Caecilius Metellus Delmaticus was a Roman politician and general. He was a son of Lucius Caecilius Metellus Calvus and brother of Quintus Caecilius Metellus Numidicus. He was consul in 119 BC; during his year, he opposed Gaius Marius' election procedures law. As consul and proconsul from 119–117 BC, he campaigned against the Dalmatians. For his victories, he triumphed in 117 BC, earning his cognomen and dedicating two temples – also contributing to repairs for the Temple of Castor and Pollux – from the spoils of war.
