Estonia–Russia border

The Estonia–Russia border, known in Estonia as the "temporary line of control" (Estonian: Ajutine kontrolljoon) is the disputed border between the Republic of Estonia (EU and NATO member) and the Russian Federation (CIS and CSTO member). The border is 294 kilometres (183 mi) long. It emerged during World War I, in 1918, as Estonia declared its independence from the then warring Russian and German Empires. The border goes mostly along the national, administrative and ethnic boundaries that have gradually formed since the 13th century. The border is a subject of Estonian–Russian dispute that was supposed to be resolved with the signing of the Border Agreement, but neither Russia nor Estonia has ratified it. It is an external border of the European Union.

In September 2022, Estonia closed its borders to most Russian citizens in response to the February 2022 Russian invasion of Ukraine. On 13 September 2023, Estonia banned vehicles with vehicle registration plates of Russia from entering its territory, in accordance with a decision by the European Union. In 2025 Estonia closed access to the Saatse boot followed the sighting of armed Russian soldiers in the disputed territory.
