Quintus Caecilius Metellus Pius Scipio, often referred to as Metellus Scipio, was a Roman senator and military commander. During the civil war between Julius Caesar and the senatorial faction led by Pompey, he was a staunch supporter of the latter. He led troops against Caesar's forces, mainly in the battles of Pharsalus and Thapsus, where he was defeated. He later committed suicide. Ronald Syme called him "the last Scipio of any consequence in Roman history."

Caesar's civil war was a civil war during the late Roman Republic between two factions led by Gaius Julius Caesar and Gnaeus Pompeius Magnus (Pompey), respectively. The main cause of the war was political tensions relating to Caesar's place in the republic on his expected return to Rome on the expiration of his governorship in Gaul.
