Kuban (Russian: Кубань; Ukrainian: Кубань; Adyghe: Пшызэ) is a geographic region of Southern Russia surrounding the Kuban River, on the Black Sea between the Don Steppe, Volga Delta and the Caucasus, and separated from the Crimean Peninsula to the west by the Kerch Strait. Krasnodar Krai is often referred to as Kuban, both officially and unofficially, although the term is not exclusive to the krai and accommodates the republics of Adygea, Karachay–Cherkessia, and parts of Stavropol Krai.
