Hasangaya (Azerbaijani: Həsənqaya) or Haykajur (Armenian: Հայկաջուր, also) is a village in the Tartar District of Azerbaijan, in the disputed region of Nagorno-Karabakh. The village had an ethnic Armenian-majority population prior to the First Nagorno-Karabakh war when the village came under Azerbaijani control.[1]
During the Soviet period, the village was located in the Mardakert District of the former Nagorno-Karabakh Autonomous Oblast.
