Lucius Caecilius Metellus Denter (born circa 320 BC) was a Roman Republican Consul in the year 284 BC.
He was either the son or the nephew of Quintus Caecilius, and the first in which the cognomen Metellus appears linked to the gentilic nomen Caecilius. He was the father of Lucius Caecilius Metellus.
He led an army against the Senones led by Britomaris in the Battle of Arretium.
There is some conflict as to the date of Metellus Denter's death, with some sources claiming he died as Consul in 284 BC in the Battle of Arretium, whereas others have him dying the year after, as Praetor, in the next battle against the Senones.
The controversy lay in that it was not customary for a Proconsul to be elected Praetor in the year after his Consulship, especially if he had been defeated in battle.
