Pyrrhias (Greek: Πυρρίας) was an Aetolian general, who was sent by his countrymen during the Social War (220–217 BC), to take the command in Elis.
Having established a fortified post on Mount Panachaikon, he laid waste the whole country as far as Rhion and Aigion.
In consequence he returned to Elis, but as the Eleans were dissatisfied with his conduct, he was shortly after recalled by the Aetolians and replaced by Euripidas.
In the spring of that year he advanced with an army to Lamia to oppose the passage of Philip V of Macedon towards the Peloponnese.
Another Pyrrhias of Aetolia was an Olympic winner in the stadion race in 200 BC, according to the Chronicon of Eusebius of Caesarea.
