The Shamkhalate of Tarki, or Tarki Shamkhalate (also Shawhalate, or Shevkalate; Kumyk: Таргъу Шавхаллыкъ, romanized: Tarğu Şawxallıq) was a Kumyk state in the eastern part of the North Caucasus, with its capital in the ancient town of Tarki. It formed on the territory populated by Kumyks and included territories corresponding to modern Dagestan and adjacent regions. After subjugation by the Russian Empire, the Shamkhalate's lands were split between the Empire's feudal domain with the same name extending from the river Sulak to the southern borders of Dagestan, between Kumyk possessions of the Russian Empire and other administrative units.
At some point the Shamkhalate had vassals from the Caspian Sea to Kabarda and Balkaria. The Shamkhals also possessed the title of the Vali of Dagestan and had their residence in the ancient Khazar-Kumyk mountainous shelter.
