Konope or Conope (Greek: Κωνώπη) and later, Arsinoe (Greek: Ἀρσινόη) or Arsinoia (Greek: Ἀρσινοί̈α), was an ancient city of Aetolia, near the eastern bank of the Achelous River, and 20 stadia from the ford of this river; near the modern village of Angelokastro (Angelókastro, Anghelokastro) in Aetolia-Acarnania, Greece. It was only a village, until it was enlarged by Arsinoe, the wife and sister of Ptolemy Philadelphus. Polybius, in his history of the Social War (220 BC-217 BC), calls it Conope, though elsewhere he calls it Arsinoe or Arsinoia. It is mentioned by Cicero under the name of Arsinoe. Near this town the river Cyathus flowed into the Achelous from the lake Hyria, which is also called Conope by Antoninus Liberalis.
