'''Femunden'''<ref>{{Cite web |title=Informasjon om stadnamn |url=https://stadnamn.kartverket.no/fakta/496891 |access-date=2024-12-30 |website=Norgeskart |publisher=Kartverket |language=no}}</ref> is Norway's third largest lake and the second largest natural lake in Norway. It is located in Innlandet and Trøndelag counties in Norway, just {{convert|13|km|mi|abbr=on}} west of the border with Sweden. The lake lies primarily in Engerdal Municipality (in Innlandet) and also smaller parts are located in Os Municipality (Innlandet) and Røros Municipality (Trøndelag). Femundsmarka National Park borders the northeastern part of the lake.<ref name="snl" />
thumb|left|200px|Map of Femund The {{convert|203.4|km2|adj=on}} lake holds about {{convert|6|km3|cumi|abbr=on}} of water and reaches a maximum depth of {{convert|150|m|ft|abbr=on}}. The surface of the lake sits about {{convert|662|m|ft|abbr=on}} above sea level.
==Name== The first element (''Fe-'' or ''Fem-'') has no known meaning, and the last element is the suffix ''-mund'' or ''-und'' (both are common in Norwegian place names). The final part ''-en'' is the definite article in the Norwegian language.<ref name="snl">{{Cite web |last=Store norske leksikon |author-link=Store norske leksikon |title=Femunden |url=http://www.snl.no/Femunden |access-date=2011-02-25 |language=no}}</ref>
==History== After Sweden had conquered the parishes of Idre and Särna in 1644, the lake Femunden was considered to be part of the border between Norway and Sweden. But this was never officially recognised by the Dano-Norwegian government (since Norway was ruled from Copenhagen in the early modern age), and during border adjustments in 1751 the Femundsmarka area east of the lake was granted to Norway from Sweden.
The new (and current) border from 1751 is quite special: For a length of {{convert|61|km}}, it makes a completely straight line between the summits of the {{convert|1002|m|adj=on}} tall mountain Våndsjögusten and the {{convert|1185|m|adj=on}} tall mountain Østerhogna. Straight-line national borders are very unusual in Scandinavia, except in the very northernmost parts.
