Gruzinsky (Russian: Грузинский; Georgian: გრუზინსკი) was a title and later the surname of two different princely lines of the Bagrationi dynasty of Georgia, both of which received it as the subjects of the Russian Empire. The name "Gruzinsky" (also spelled Gruzinski, or Gruzinskii) derives from Russian, originally and literally meaning "of Georgia". These families are:
- Princes Gruzinsky ("the Elder House"), an offshoot of the House of Mukhrani dispossessed of the throne of Kartli in 1726. They descended from Prince Bakar of Georgia (1699/1700-1750) who had removed to Russia in 1724, and went extinct with the death of Pyotr Gruzinsky (1837–1892). The family had estates in the governorates of Moscow and Nizhegorod, and was confirmed among the princely nobility of Russia in 1833.
- Princes Gruzinsky (Bagration-Gruzinsky; "the Younger House"), an offshoot of the House of Kakheti (after 1462) and (after 1744) of Kartli. The title of Prince(ss) Gruzinsky (Serene Prince[ss] after 1865) were conferred upon the grandchildren of the penultimate Georgian king Erekle II (1720/1-1798) after the Russian annexation of Georgia in 1801. Descendants of Prince Bagrat (1776–1841), grandson of Erekle II and son of the last king of Georgia George XII (1746–1800), still survive in Georgia. The current head of this family, Nugzar Bagration-Gruzinsky (born 1950), claims the legitimate headship of the Royal House of Georgia (also claimed by the line of Bagrations of Mukhrani) based on male primogeniture descent from the last king of Georgia. As he has no male issue, Evgeny Petrovich Gruzinsky (born 1947), the great-great grandson of Bagrat's younger brother Ilia (1791–1854), who lives in the Russian Federation, is considered to be an heir presumptive within the same primogeniture principle.
