Ağcayazı is a village in the Lachin District of Azerbaijan.
The village was located in the Armenian-occupied territories surrounding Nagorno-Karabakh, coming under the control of ethnic Armenian forces during the First Nagorno-Karabakh War in the early 1990s. The village subsequently became part of the breakaway Republic of Artsakh as part of its Kashatagh Province, referred to as Arjadzor (Armenian: Արջաձոր). It was returned to Azerbaijan as part of the 2020 Nagorno-Karabakh ceasefire agreement.
