Kistin Gorge or Armkhi Gorge is a gorge of the Armkhi River in the Dzheyrakhsky District of the Republic of Ingushetia. The name of the gorge comes from the historical name of the river Armkhi – Kistinka, which in turn comes from one of the ethnonyms of the Ingush – Kists. Historically, the area where the gorge is located was called "Kistetia". It is mentioned in medieval Georgian sources, in particular, in the work of Vakhushti Bagrationi.
