The Nukha uezd was a county (uezd) of the Elizavetpol Governorate of the Russian Empire and later of the Azerbaijan Democratic Republic with its center in Nukha (present-day Shaki) from 1868 until its formal abolition in 1921 by the Soviet authorities of the Azerbaijan SSR.

The Nukha uezd was located in the far northeastern part of the Elizavetpol Governorate, bordering the Dagestan Oblast to the north, the Baku Governorate to the east, the Zakatal Okrug to the west, and the Aresh uezd to the south. The administrative center of the Nukha uezd was the city of Nukha. The northern part of the county was largely mountainous and laid along the Greater Caucasus mountain range, where the altitude reaches as high as 14-15 thousand feet in altitude. The notable peaks of the district included Mount Bazardüzü (14,722 ft) and Tkhfan Dag (13,764 ft) whose valleys were enriched with many rivers. The southern part of the region possessed the best conditions for agricultural use including gardening, harvesting rice and sericulture. The main rivers in the Nukha uezd were Shin-chay, Kish-chay, Ajighan-chay, Turyanchay, Goychay which were used for irrigation purposes.

After the establishment of Russian rule over the khanates in the South Caucasus and the implementation of administrative reforms, the territories of the erstwhile Shaki Khanate were incorporated into Shamakhi Governorate of the Russian Empire, later ebing renamed to the Baku Governorate. Upon establishment of the Elizavetpol Governorate in 1868, the Nukha uezd was transferred from the Baku to Elizavetpol Governorates. In 1874, the southern section of Nukha uezd was separated to form the Aresh uezd within the same governorate. On 30 August 1918, the Elizavetpol Governorate was officially renamed to the Ganja Governorate in an effort by the authorities of the Azerbaijan Democratic Republic to de-Russify the region of its Tsarist toponyms.
