Lachin corridor was a six-kilometer mountain corridor in Azerbaijan that connected Armenia and the self-proclaimed Republic of Artsakh. The territory of the corridor today consists of three settlements: the villages of Zabukh, Sus and the city of Lachin.
After the First Nagorno-Karabakh War in 1994, the area was occupied by the Nagorno-Karabakh Republic. Following the 2020 Nagorno-Karabakh war it was controlled by Russian peacekeepers. In 2023, Armenia took control of Artsakh/Nagorno-Karabakh. Almost all the Armenians in Artsakh left through the Lachin corridor to Armenia.
