Lucius Aemilius Paullus Macedonicus was a two-time consul of the Roman Republic and general, who conquered Macedon in the Third Macedonian War.

The gens Aemilia, originally written Aimilia, was one of the greatest patrician families at ancient Rome. The gens was of great antiquity, and claimed descent from Numa Pompilius, the second King of Rome. Its members held the highest offices of the state, from the early decades of the Republic to imperial times. The Aemilii were almost certainly one of the gentes maiores, the most important of the patrician families. Their name was associated with three major roads, an administrative region of Italy, and the Basilica Aemilia at Rome.
