Quintus Fabius Maximus Aemilianus was a Roman statesman and consul (145 BC). Fabius was by adoption a member of the patrician gens Fabia, but by birth he was the eldest son of Lucius Aemilius Paullus Macedonicus and Papiria Masonis and the elder brother of Scipio Aemilianus. He was the father of Quintus Fabius Maximus Allobrogicus. Fabius and his brother were the pupils and patrons of the historian Polybius, who recorded the strong fraternal bond between the brothers, even after their adoption into other houses.
