{{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&nbsp;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&nbsp;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&nbsp;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>
