Parnaoz (Georgian: ფარნაოზი; Russian: Парнаоз Ираклиевич Грузинский, Parnaoz Irakliyevich Gruzinsky) (14 February 1777 – 30 March 1852) was a Georgian prince (batonishvili) of the Bagrationi dynasty, the 14th son of Heraclius II, the penultimate king of Kartli and Kakheti, by his third marriage to Queen Darejan Dadiani. Parnaoz tried to challenge the recently established Imperial Russian rule in Georgia and in 1804 headed an unsuccessful insurrection of the Georgian mountaineers in the course of which he was arrested and deported to Russia. Afterwards, he spent most of his life in St. Petersburg, becoming the first Georgian translator of the 18th-century French philosopher Jean-Jacques Rousseau.
Parnaoz's active involvement in the politics of his country came with the accession of his half-brother, George XII, to the throne of Kartli and Kakheti after the death of Heraclius II in 1798. George reversed the rule of succession approved in 1791 by Heraclius under the influence of Queen Darejan, requiring the king's successor to pass the throne not to his offspring, but to his eldest brother. This would have made Parnaoz the 6th in the line of succession, behind George and his elder brothers, Iulon, Vakhtang, Mirian, and Alexander. Instead, the new monarch, having renewed quest for Russian protection, obtained from Paul I of Russia recognition of his son, David, as heir-apparent on 18 April 1799. This gave rise to a dynastic dispute, in which Parnaoz stood by Iulon's side.
