House of Berzeg (ਨ) (Ubykh: Барзагь, Adyghe: Бэрзэдж, Russian: Берзег, Turkish: Berzeg Ailesi) is a Circassian princely house of Ubykhia of Circassia, who controlled the entirety of valley of the Sochi River (on its right bank, two hours from the sea) and entirety of the Mytykhuasua[1] (now Plastunka) village of Ş̂açə (Sochi) until the end of Russo-Circassian War.

[5] While the family is Ubykh and originated in Ubykhia, there are branches among other Circassian tribes.

The house was a close ally and had kinship ties with the Shuwpagwe clan of the Natukhajs.

After 1838, Ismail Berzeg acted as a diplomat between Circassia and England.

Berzeg members are found in Adygea and Krasnodar Krai within Russian Federation; as well as in Republic of Turkey due to Circassian genocide in the present day.
