The Circassian diaspora refers to ethnic Circassian people around the world who live outside their homeland Circassia. The majority of the Circassians live in the diaspora, as their ancestors were settled during the resettlement of the Circassian population, especially during the late nineteenth and early twentieth century. From 1763 to 1864, the Circassians fought against the Russian Empire in the Russian-Circassian War, finally succumbing to a scorched-earth genocide campaign initiated between 1862 and 1864. Afterwards, large numbers of Circassians were exiled and deported to the Ottoman Empire and other nearby regions; others were resettled in Russia far from their home territories. Circassians live in more than fifty countries, besides the Republic of Adygea. Total population estimates differ: according to some sources, some two million live in Turkey, Jordan, Syria, and Iraq; other sources say between one and four million live in Turkey alone.

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.
