Armenia–Artsakh relations

Armenia–Artsakh relations were the foreign relations between the former unrecognized Republic of Artsakh and Armenia. The Republic of Artsakh controlled most of the territory of the former Nagorno-Karabakh Autonomous Oblast (before the 2020 Nagorno-Karabakh war, it also controlled some of the surrounding area). Artsakh had very close relations with Armenia. It functioned as a de facto part of Armenia. A representative office of Nagorno-Karabakh exists in Yerevan.
