Kartlos (Georgian: ქართლოსი) is the eponymous ancestor of the Georgians (Kartvelians) in Georgian mythology, more specifically of the nation of Kartli (Caucasian Iberia). Kartlos is introduced in the medieval Georgian Chronicles (Kartlis Cxovreba), presumably recorded 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 Haos, Movakos, Lekos, Heros, Kavkasos, and Egros from whom other Caucasian peoples took their origin. Kartlos united his people to become their chieftain and founded the city of Kartli.
The sons of Kartlos are listed as: Mtskhetos, Gardabos, Kakhos, Kukhos, Gachios, Uphlos, Odzrkhos, Javakhos, the respective eponymous founders of Mtskheta, Gardabani, Kakheti, Kukheti, Gachiani, Uplistsikhe, Odzrkhe, and Javakheti.
