Caucasian Albania is a modern exonym for a former state located in ancient times in the Caucasus, mostly in what is now Azerbaijan. The modern endonyms for the area are Aghwank and Aluank, among the Udi people, who regard themselves as descended from the inhabitants of Caucasian Albania. However, its original endonym is unknown.

The Caucasus, or Caucasia, is a transcontinental region between the Black Sea and the Caspian Sea, mainly comprising Armenia, Azerbaijan, Georgia, and parts of Southern Russia. The Caucasus Mountains, including the Greater Caucasus range, have historically been considered as a natural barrier between Eastern Europe and West Asia.
