Hadrut District (; ) was an administrative unit within the former Nagorno-Karabakh Autonomous Oblast (NKAO) of the Azerbaijan Soviet Socialist Republic.
The district was formed on 8 August 1930, as the Dizak district; it was renamed Hadrut District on 17 September 1939. The administrative center of the district was the town of Hadrut.
The total area of the district was 679 km<sup>2</sup> and it included 41 villages (1986).
Along with NKAO, the district was abolished on 26 November 1991 and was incorporated into Khojavend District of Azerbaijan.
Following the First Nagorno-Karabakh war, the former district came under the control of the self-proclaimed Republic of Artsakh and was incorporated into its Hadrut Province. However, during the 2020 Nagorno-Karabakh war, Azerbaijan recaptured the town of Hadrut during the Battle of Hadrut, followed by the whole of the district.
