Üçüncü Ağalı is a village in the Zangilan 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, subsequently becoming part of the breakaway Republic of Artsakh as part of its Kashatagh Province, being referred to as Aghadzor (Armenian: Աղաձոր). It was recaptured by Azerbaijan on 21 October 2020 during the 2020 Nagorno-Karabakh conflict.[2]
