Sweden has two neighboring countries that it shares a land border with: Norway to the west and north, and Finland to the northeast. Together these land frontiers stretch roughly 2,233 km, almost the entire length of which lies in the sparsely populated far north of the Scandinavian Peninsula.
Norway: Sweden's Longest Land Border
Norway is by far Sweden's longest neighbor, with a shared border of around 1,630 km. It begins near the Skagerrak strait in the south and runs north-northeast through dense forest, mountain plateaus and tundra before ending near the Treriksröset cairn in Lapland. For much of its length the boundary follows the watershed ridge of the Scandinavian Mountains (Scandes), the natural spine that divides the peninsula.
Despite the rugged terrain, this is one of the most open and friendly borders in the world. Both countries belong to the Nordic Passport Union and the European Economic Area, so people, goods and services cross with little friction. Towns such as Sweden's Strömstad and Norway's Halden see heavy cross-border shopping traffic, with Norwegians frequently driving into Sweden for cheaper groceries.
Finland: The Northeastern Neighbor
Finland shares a land border of roughly 545 km with Sweden, running along the far north of the Gulf of Bothnia. The boundary largely follows the Torne (Torne älv) and Muonio rivers, a watery frontier that has separated the two states since 1809, when Sweden ceded Finland to the Russian Empire after the Finnish War.
The border splits the "Torne Valley," a region where a Finnish-related dialect called Meänkieli is still spoken on the Swedish side. The twin towns of Haparanda (Sweden) and Tornio (Finland) are so closely intertwined that they share a joint town center, a single golf course straddling the line, and coordinated public services. Both nations are now members of the European Union, deepening this everyday integration.
Treriksröset: Where Three Nations Meet
At the northernmost tip of the land borders sits Treriksröset, a yellow concrete cairn marking the tripoint where Sweden, Norway and Finland meet. It is Sweden's northernmost point and a popular, if remote, hiking destination reached only on foot or by boat across Lake Goldajärvi. The marker is a vivid reminder that all of Sweden's land neighbors are clustered in the Arctic and sub-Arctic north, while the densely populated south faces the sea.
Maritime Neighbors Across the Baltic
Although Sweden touches only two countries by land, it has many close neighbors across the water. The Baltic Sea, the Gulf of Bothnia, the Kattegat and the Öresund strait give Sweden maritime boundaries and short sea links with several nations:
- Denmark lies just across the Öresund, connected to Sweden by the famous Öresund Bridge linking Malmö and Copenhagen.
- Germany and Poland sit to the south across the Baltic, served by ferry routes from ports such as Trelleborg and Ystad.
- Estonia, Latvia and Lithuania, the Baltic states, face Sweden's east coast and have growing trade and ferry ties.
- Russia shares a distant maritime boundary in the eastern Baltic.
These sea connections have shaped Sweden's history of trade, the Hanseatic League and naval power for centuries, even though they do not appear on a map of land frontiers.
How the Borders Were Formed
Sweden's modern boundaries are the product of long rivalries and treaties. For much of the medieval and early modern period, Sweden and Norway were both linked at various times to Denmark, and Finland was an integral part of the Swedish realm. The 1809 loss of Finland fixed the eastern river border, while the dissolution of the Swedish-Norwegian union in 1905 confirmed the western boundary as a frontier between two fully independent kingdoms. Today these are peaceful, demilitarized borders maintained through close Nordic cooperation. For a wider overview of the country, see our sweden country guide.
Frequently Asked Questions
How many countries border Sweden by land?
Sweden borders two countries by land: Norway and Finland. Both lie along the northern and western edges of the Scandinavian Peninsula, with the longest stretch shared with Norway.
Does Sweden share a border with Denmark?
Not by land. Denmark is one of Sweden's closest neighbors, but the two are separated by the Öresund strait. They are joined by the Öresund Bridge and tunnel between Malmö and Copenhagen, making it a maritime and infrastructure connection rather than a land border.
What is the longest border Sweden has?
The border with Norway is the longest, at about 1,630 km. It follows the Scandinavian Mountains for much of its length and is the longest continuous border in the Nordic region.
Where do Sweden, Norway and Finland meet?
The three countries meet at Treriksröset, a cairn in the far north of Lapland. It marks both the tripoint of the three nations and the northernmost point of Sweden.
