{{for|the modern town|Lasiona, Elis}} '''Lasion''' ({{langx|el|Λασίων}} or Λασιών) was the chief town of the mountainous district of [[Acroreia]] in [[ancient Elis]] proper, situated upon the frontiers of [[ancient Arcadia|Arcadia]] near [[Psophis]]. Lasion was a frequent object of dispute between the Arcadians and Eleians, both of whom laid claim to it. In the war which the [[ancient Sparta|Spartans]] carried on against Elis at the close of the [[Peloponnesian War]], [[Pausanias of Sparta|Pausanias]], king of [[Sparta]], took Lasion.<ref>{{Cite Diodorus|14.17}}</ref> The invasion of Pausanias is not mentioned by [[Xenophon]] in his account of this war; but the latter author relates that, by the treaty of peace concluded between Elis and Sparta in 400 BCE, the Eleians were obliged to give up Lasion, in consequence of its being claimed by the Arcadians.<ref>{{Cite Hellenica|3.2.30}}</ref> In 366 BCE, the Eleians attempted to recover Lasion from the Arcadians; they took the town by surprise, but were shortly afterwards driven out of it again by the Arcadians.<ref>{{Cite Hellenica|7.14.13}} ''et seq.''</ref><ref>{{Cite Diodorus|15.77}}</ref> In 219 BCE, Lasion was again a fortress of Elis, but upon the capture of Psophis by [[Philip V of Macedon]], the Eleian garrison at Lasion straightway deserted the place; after Philip took the town, he gave it to the [[Achaean League|Achaeans]].<ref>{{Cite Polybius|4.72, 73}}</ref> [[Polybius]] mentions along with Lasion a fortress called [[Pyrgus (Elis)|Pyrgus]], which he places in a district named Perippia.<ref>{{Cite Polybius|5.102}}</ref>
It is located in the upper [[Ladon (river)|Ladon]] valley, north of modern [[Koumani]].<ref>{{Cite DARE|30996}}</ref><ref>{{Barrington Atlas|page=58}}</ref>
