Finland shares land borders with three countries: Sweden to the west, Norway to the north, and Russia to the east, with a combined land boundary of roughly 2,563 km. It also faces Estonia across the Gulf of Finland as a close maritime neighbour. Each of these frontiers tells a different story about Finland's geography, history, and place in modern Europe.
The Three Land Neighbours at a Glance
Finland is a Nordic country occupying the north-eastern edge of the Baltic region, and its land borders fan out along its northern and western edges. Going clockwise from the east:
- Russia — to the east, about 1,340 km of border, by far Finland's longest.
- Norway — to the north, roughly 736 km, running through Arctic Lapland.
- Sweden — to the west, around 614 km, much of it following the Tornio (Torne) River.
The southern and western coasts of Finland are washed by the Baltic Sea, the Gulf of Bothnia, and the Gulf of Finland, which is why the country has no land border to the south. Estonia lies just across that southern gulf, only about 80 km from Helsinki.
Russia: The Long Eastern Frontier
The Finnish–Russian border is the longest of the three and one of the most significant. Stretching about 1,340 km from the Gulf of Finland in the south to the Arctic region near Norway in the north, it forms one of the European Union's longest external land borders. This frontier has shifted dramatically over the past century. Finland was an autonomous Grand Duchy within the Russian Empire from 1809 until it declared independence in 1917. The border was redrawn after the Winter War (1939–1940) and the Continuation War, when Finland ceded large territories including much of Karelia and the city of Vyborg. Today the border runs through dense forest and lake country, with major crossing points such as Vaalimaa and Nuijamaa historically handling heavy trade and tourist traffic.
Norway: The Arctic North
To the north, Finland meets Norway along roughly 736 km of border that lies almost entirely within the Arctic Circle in the region of Lapland. This is a land of tundra, fells, reindeer herding, and the midnight sun in summer and polar night in winter. The border zone is home to the Sámi, the Indigenous people whose traditional territory, Sápmi, spans Finland, Norway, Sweden, and Russia without regard to modern political lines. The northernmost point of mainland Finland sits near this frontier, and the three-country cairn (Treriksröset) where Finland, Norway, and Sweden meet is a popular hiking landmark.
Sweden: The Riverine Western Border
Finland's western neighbour, Sweden, shares about 614 km of border, much of it traced by the Tornio (Torne) and Muonio rivers flowing toward the Gulf of Bothnia. The twin towns of Tornio (Finland) and Haparanda (Sweden) sit directly across from each other and function almost as a single cross-border community. Finland and Sweden have deeply intertwined histories: Finland was part of the Kingdom of Sweden for roughly 600 years, until 1809. That legacy survives in the Swedish-speaking minority in Finland and the status of Swedish as an official language. As fellow members of the Nordic Passport Union, citizens move freely across this border with minimal formalities.
Estonia and Finland's Maritime Edge
While Finland has only three land neighbours, its closest maritime neighbour is Estonia, lying directly south across the Gulf of Finland. The crossing between Helsinki and Tallinn is among the busiest passenger ferry routes in the world, with travellers making the trip in a couple of hours. Linguistically and culturally the two nations are close cousins: Finnish and Estonian are both Finnic languages and are partly mutually intelligible. Finland also shares Baltic Sea waters with Sweden and Russia, and trade, tourism, and environmental cooperation across the Baltic remain central to the region's economy.

Frequently Asked Questions
How many countries border Finland?
Finland borders three countries by land: Sweden, Norway, and Russia. If you include maritime neighbours, Estonia lies just across the Gulf of Finland to the south.
Which country has the longest border with Finland?
Russia has the longest border with Finland at about 1,340 km, making it one of the longest external land borders of the European Union.
Does Finland share a border with Estonia?
Finland does not share a land border with Estonia. The two countries are separated by the Gulf of Finland, a maritime boundary about 80 km wide at its narrowest, and are linked by frequent ferries between Helsinki and Tallinn.
Is Finland part of Scandinavia?
Geographically, Scandinavia usually refers to Norway, Sweden, and Denmark, so Finland is not strictly Scandinavian. However, Finland is firmly part of the broader Nordic region alongside those countries and Iceland, sharing close political, cultural, and economic ties.
