Antipater Etesias (Greek: Ἀντίπατρος Ἐτησίας, Ἀntípatros Ἐtēsías) was a king of Macedon.
The Macedonians gave Antipater the name Etesias, because the etesian winds blew during the short time that he was king.
Despite this he still had a following in some parts of Macedon and was defeated by Antigonus II Gonatas.
After this he fled to Egypt where he is mentioned 20 years later, encouraged by the king Ptolemy III Euergetes as a potential rival claimant to the Macedonian throne.
