Caucas or Kavkasos (Georgian: კავკასოსი, romanized: k'avk'asosi) was the supposed ancestor of Vainakh peoples (Chechens and Ingush) according to The Georgian Chronicles. His story is narrated in the compilation of the medieval Georgian chronicles, Kartlis Tskhovreba, taken down from oral tradition by Leonti Mroveli in the 11th century. The legend has it that he was a son of Targamos and, thus, brother of Hayk (known to be ancestor of Armenian people), Movakos, Lekos (referred to as the ancestor of Lezgic peoples), Heros, Kartlos (known to be ancestor of Georgian people), and Egros.

Caucas' descendant Dzurdzuk is said to be the ancestor of the Chechens and Ingush.^[1]
