Narva is a municipality and city in Estonia. It is located in the Ida-Viru County, at the eastern extreme point of Estonia, on the west bank of the Narva river which forms the Estonia–Russia international border. With 53,626 inhabitants Narva is Estonia's third largest city after capital Tallinn and Tartu.

The Estonia–Russia border is the international border between the Republic of Estonia and the Russian Federation. 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 exact location of the border was a subject of Estonian–Russian dispute that was resolved with the signing of the Border Agreement, but neither Russia nor Estonia have completed its ratification yet. It is an external border of the European Union.
