Azerbaijan–Turkey border
The Azerbaijan–Turkey border (Azerbaijani: Azərbaycan–Türkiyə sərhədi, Turkish: Azerbaycan–Türkiye sınırı) is a 17 km (11 mi) long international border between the Republic of Azerbaijan and the Republic of Turkey. The border is located at the southeastern tip of the Iğdır Province on the Turkish side and at the northwestern tip of the Nakhchivan Autonomous Republic on the Azerbaijani side; running entirely along the Aras river, it is the shortest border for both countries.
