Plautius Quintillus (died by 175) was a Roman Politician that lived in the Roman Empire in the 2nd century. The family of Plautius Quintillus was of consular rank from Rome and was politically active during the rule of Nerva–Antonine dynasty in the 2nd century. Quintillus’ birth name could have been Lucius Titius Plautius Quintillus. His father was probably Lucius Titius Epidius Aquilinus, who served as consul in 125 under the Roman Emperor Hadrian. According to a preserved incomplete inscription found in Rome, Aquilinus may have been the head of a priestly college and could have hosted a public entertainment event held in Rome. His brother may have been Lucius Titius Plautius Aquilinus who served as consul in 162 under the Roman Emperors Marcus Aurelius and Lucius Verus.
