The Kazakh uezd was a county (uezd) of the Elizavetpol Governorate of the Russian Empire and later of the Azerbaijan Democratic Republic with its center in Kazakh (present-day Qazax) from 1868 until its formal abolition in 1929 by the Soviet authorities of the Azerbaijan SSR. The area of the Kazakh uezd forms a large part of the modern-day Tavush Province and a small northeastern part of the Gegharkunik Province of Armenia, also forming most of the area of the Agstafa, Tovuz and Qazax districts of Azerbaijan.
