The Abazin, Abazinians or Abaza (Abaza and Abkhaz: Абаза; Circassian: Абазэхэр; Russian: Абазины; Turkish: Abazalar; Arabic: أباظة) are an ethnic group of the Northwest Caucasus, closely related to the Abkhaz and Circassian peoples. Today, as a result of atrocities committed by Imperial Russia during the Circassian genocide, they live mostly in Turkey, Syria, Jordan, Egypt and in Karachay-Cherkessia and Stavropol Krai in the North Caucasus region of Russia. The Tapanta (ru:Тапанта), a branch of the Abaza, lived between the Besleney and Kabardian princedoms on the upper Kuban.
Abaza people historically speak the Abaza language, a Northwest Caucasian language most closely related to Abkhaz, and more distantly related to the Ubykh and Circassian languages. There are two dialects of Abaza spoken in Karachay-Cherkessia: Ashkharua and Tapanta. The culture and traditions of the Abazin are similar to those of the Circassians. On many old maps Abazin territory is marked as part of Circassia (Adygea).
