Of Norway, Sweden, and Finland, which, if any, share a land border with Russia?

While all three nations occupy the Fennoscandian Peninsula, their geographic positions create very different relationships with their large eastern neighbor. Finland shares a lengthy 1,340-kilometer (833-mile) border with Russia, the longest of any European Union country. To the north, Norway also shares a short but strategically important 196-kilometer (122-mile) border in the high Arctic. Sweden, however, is geographically separated from Russia, buffered by Norway to its west and Finland to its east.

The Finnish-Russian border is deeply rooted in a complex history. For over a century, Finland existed as an autonomous grand duchy within the Russian Empire before gaining independence in 1917. This border was later the site of intense conflict during the Winter War of 1939-1940. More recently, its geopolitical significance was underscored by Finland's decision to join NATO in 2023, effectively doubling the alliance's direct land border with Russia.

Norway's border is much shorter and more remote, running through Arctic wilderness to the Barents Sea. As a founding member of NATO, this has long been a sensitive frontier, representing the northernmost meeting point between the alliance and Russia. While Sweden does share a maritime border with Russia's Kaliningrad exclave across the Baltic Sea, it lacks any direct land connection, making it the outlier among the three Nordic countries.
