The Circassians or Circassian people, also called Cherkess or Adyghe are a Northwest Caucasian ethnic group and nation who originated in Circassia, a region and former country in the North Caucasus. As a consequence of the Circassian genocide, which was perpetrated by the Russian Empire during the Russo-Circassian War in the 19th century, most of the Circassian people were exiled from their ancestral homeland and consequently began living in what was then the Ottoman Empire—that is, modern-day Turkey and the rest of the Middle East. In the early 1990s, the Unrepresented Nations and Peoples Organization estimated that there are as many as 3.7 million Circassians in diaspora in over 50 countries.

Adyghe is a Northwest Caucasian language spoken by the western subgroups of Circassians. It is spoken mainly in Russia, as well as in Turkey, Jordan, Syria and Israel, where Circassians settled after the Circassian genocide by the Russian Empire. It is closely related to the Kabardian language, though some reject the distinction between the two languages in favor of both being dialects of a unitary Circassian language.
