The Circassian Union and Charity Society (Adyghe: Адыгэ Зэготын ыкӀи ЗэдэӀэпыӀэн Хасэ) or Çerkes İttihat ve Teavün Cemiyeti (Ottoman Turkish: چركس اتحاد و تعاون جمعیتی) was a Circassian nationalist charitable organization in the Ottoman Empire.

[4] Before the end of the Russo-Circassian War in 1864, a mass deportation was launched against the remaining population who survived the Circassian genocide.

[5] Calculations including those taking into account the Russian Imperial Government's own archival figures have estimated a loss of 95–97%[6][7][8][9] of the Circassian nation in the process.

The Ottoman authorities assigned lands for Circassian settlers close to regular water sources and grain fields.

[11] Circassians in the Ottoman Empire initially kept to themselves and maintained their separate identity, even having their own courts, in which they would tolerate no outside influence.

A large portion of influential entities, such as the Ottoman Special Organization, Hamidiye regiments, and the Committee of Union of Progress were made up by Circassians.

In August 1908, the first members laid the foundation of the Circassian Union and Charity Society in the mansion of Imam Shamil's son Gazi Mehmet Pasha in Koska, Istanbul.

People in the organization held a variety of ideological beliefs, including those who supported the Committee of Union and Progress (CUP) and others who opposed it.

Even the most passionate supporters and opponents of the CUP were united in the organization with the same purpose in mind: to start the Circassian cultural renaissance.
