The Armenia–Turkey border is 311 km in length and runs from the tripoint with Georgia in the north to the tripoint with Azerbaijan in the south. The land border has been closed since 3 April 1993. The border has been protected by guards of the Russian Federal Security Service since 1992. On 9 May 2024, Russian Presidential spokesman Dmitry Peskov announced that Russian border guards will continue to serve on Armenia's borders with Turkey and Iran, at the request of the Armenian side. The border is set to reopen for diplomats and citizens of third countries in 2023.

Bagaran is a village in the Armavir Province of Armenia near the Armenia–Turkey border. Its name is derived from the nearby ancient Armenian city of Bagaran which was a large city and fortress that straddled both banks of the Akhurian River, and served as a former capital of medieval Armenia. A small Kurdish-populated village called Kılıttaşı now partially lies on the Turkish side of the closed border.
