Aeropus II (Ancient Greek:Ἀέροπος,romanized: Aéropos), son ofPerdiccas II, was king ofMacedonia from 398/7 until his death from illness in July or August of 394/3 BC.^[2][3] He first governed as guardian (epitropos)^[a] for his young nephewOrestes whenArchelaus died in 400/399 BC. However,Diodorus reports that Aeropus murdered Orestes three years later, but it is also possible that he had simply won the support of the Macedonian nobility.^[5][6] As king, he might have taken the name Archelaus.^[1] Aeropus had a son namedPausanias, but was succeeded instead byAmyntas II, possibly son of his great-uncle Menelaus.^[7]

Two traditions relate how Aeropus was overawed by either the insolence^[8][9] or the stratagems^[10] of the Lacedaemonian kingAgesilaus, allowing his armies free passage through Macedonia after their campaign in Asia.

There is a minority view among scholars that Aeropus was aLyncestian prince, rather than anArgead, who married into the dynasty, therefore enabling him later to become regent for Orestes.^[11] However, the majority of historians believe Aeropus to have been Perdiccas' son and thus a member of the dynasty.^{[2][7][12][13]}
