Amynander (Ancient Greek: Ἀμύνανδρος, Amynandros, in Polybios also Amynas) was king of the Athamanes in south Epirus, following his predecessor Theodorus of Athamania. He was a brother-in-law of the Illyrian king Scerdilaidas and first appears in history as a mediator between Philip V of Macedon and the Aetolians.
When the Romans were about to wage war on Philip, they sent ambassadors to Amynander to inform him of their intention. On the commencement of the war, he came to the camp of the Romans and promised them assistance: the task of bringing over the Aetolians to an alliance with the Romans was assigned to him.
