Gurgen II "the Great" (Georgian: გურგენ II დიდი, Gurgen Didi) (died February 14, 941) was a Georgian prince of the Bagratid dynasty of Tao-Klarjeti and hereditary ruler of Tao with the title of eristavt-eristavi, "duke of dukes".
The son of Adarnase III of Tao, Gurgen succeeded on the death of his paternal uncle Ashot Kukhi in 918.
Gurgen was an energetic ruler and accumulated in his hands much power, ruling over Tao, parts of Klarjeti and Javakheti, and also Adjara and Nigali.
Thus, sometime between 923 and 941, he wrested Klarjeti from his father-in-law Ashot "the Prompt", son of Bagrat I, giving him two other domains — western part of Javakheti and Adjara — in exchange.
With Gurgen’s death in 941, the Bagratid line of Tao became extinct and his state was divided among other branches of the dynasty.
