Borders of Russia

• 1. Introduction

  ›

  The borders of Russia stretch for more than 22,400 kilometers of recognized land boundary, making Russia the country with the second-longest land border on Earth. Only China surpasses it, by a margin of just 50 kilometers. Russia touches fourteen sovereign nations by land, and its coastlines carry narrow maritime boundaries with two more: the United States and Japan. How a territory this vast drew its lines, and what has happened to those lines in living memory, is a story that reaches from the Baltic Sea to the Pacific Ocean.

• 2. The Long Neighbor to the South

  ›

  The Kazakhstan-Russia border alone runs 7,512.8 kilometers, making it the longest single land boundary Russia shares with any country. That single border accounts for roughly a third of Russia's total recognized land perimeter. Stretching across open steppe, it is one of the longest bilateral land borders anywhere on the planet. South of Kazakhstan, the China-Russia border runs 4,209.3 kilometers, and Mongolia adds another 3,485 kilometers of shared frontier. These three neighbors alone define the bulk of Russia's southern exposure.

• 3. The European Frontiers

  ›

  Belarus contributes the longest of Russia's European land borders, at 1,925.8 kilometers. Norway and Poland each share borders exceeding 1,200 kilometers with Russia. The smaller Baltic-region states, Estonia, Latvia, and Lithuania, each maintain borders measured in the low hundreds of kilometers. Finland's land border with Russia runs 138 kilometers, though its maritime component adds another 322 kilometers. These borders were mostly drawn in their current form since 1956, with only minor subsequent adjustments, and they held their shape through the dissolution of the Soviet Union.

• 4. Where Land Meets Sea

  ›

  Russia's maritime reach extends far beyond its shoreline contacts with the United States and Japan. The Pacific Ocean alone accounts for nearly 17,000 kilometers of maritime boundary in Russia's border total. The Arctic Ocean adds more than 19,700 maritime kilometers. The Black Sea and Caspian Sea each carry their own maritime segments, with the Caspian running 580 kilometers. Japan's maritime boundary with Russia measures 194.3 kilometers, while the formal USSR-USA Maritime Boundary Agreement defines a corridor of 49 kilometers between the two countries.

• 5. Breakaway Borders

  ›

  Two territories bordering Russia are not internationally recognized sovereign states: Abkhazia and South Ossetia, both of which broke from Georgia. The Abkhazia-Russia border runs 572.5 kilometers of land, with a further 22.4 kilometers of maritime boundary. South Ossetia shares 70 kilometers with Russia. Georgia's own recognized border with Russia sits at 327.6 kilometers. These breakaway territories create a zone where political geography and legal geography diverge.

• 6. The Ukrainian Redrawing

  ›

  In 2014, Russia annexed Ukraine's Crimean peninsula in a move that the international community has not recognized. That annexation shifted de facto borders between Russia and Ukraine without altering the internationally accepted line. Then in 2022, Russia annexed four additional Ukrainian regions: Donetsk, Kherson, Luhansk, and Zaporizhzhia oblasts. Each annexation deepened the gap between the borders Russia claims to hold and the borders the world records on official maps. The Belarus-Russia border, at 1,925.8 kilometers, now sits alongside a Ukrainian boundary that exists in two competing versions depending on whose accounting you follow.
