Agelaus of Naupactus (), was a leading official in the Aetolian League. He is first mentioned when in 221 BC he negotiated an alliance between the lllyrian chief Scerdilaidas and the Aetolians. It was through his persuasive speech that Philip V of Macedon and his allies were induced to make peace with the Aetolians after the Social War (220–217 BC) and he was elected general of the Aetolians in the following year, though his conduct in recommending peace was soon afterwards criticized by his fickle countrymen.
