Ioane (Georgian: იოანე ბაგრატიონი) (16 May 1768 – 15 February 1830) was a Georgian prince (batonishvili), writer, lexicographer and encyclopaedist.^[1]

A son of George XII, the last king of Kartli-Kakheti kingdom, eastern Georgia, by his first wife Ketevan Andronikashvili, Ioane commanded an avant-garde of a Georgian force annihilated by the Persian army at the Battle of Krtsanisi in 1795.^{[citation needed]}

Following the battle, the kingdom entered a period of economic crisis and political anarchy. To eradicate the results of a Persian attack and to overcome the retardation of the feudal society, Prince Ioane proposed on 10 May 1799, a project of reforms of administration, army and education. This project was, however, never materialized due to the weakness of George XII and a civil strife in the country. In 1800, he commanded a Georgian cavalry in the joined Russian-Georgian forces that defeated his uncle, Alexandre Bagrationi, and the Dagestani allies at the Battle of Niakhura.^{[citation needed]}

Upon the death of George XII, Kartl-Kakheti was incorporated into the expanding Russian Empire, and Ioane was deported to Russia. He settled in Saint Petersburg where he wrote most of his works with a didactic encyclopedic novel Kalmasoba (1817–1828) being the most important of them.^{[citation needed]}

He is also an author of a naturalist encyclopedia (1814), a children encyclopedia (1829), a Russian-Georgian dictionary, a Georgian lexicon, and of several poems.^{[citation needed]}

His manuscripts were discovered in 1861 by a Georgian scholar, Dimitri Bakradze, who published them in an abridged version in 1862.^{[citation needed]}

He married in 1787, Princess Ketevan Tsereteli (1775–1832), daughter of Prince Zurab Tsereteli (1747–1823), Mayor of the Palace (sakhlt-ukhutsesi) of Imereti, and had the only son, Grigol.^{[citation needed]}
