The House of Orbeliani (Georgian: ორბელიანი) was a Georgian noble family (tavadi), which branched off the House of Baratashvili in the 17th century and later produced several lines variously called Orbeliani, Orbelishvili (ორბელიშვილი), Qaplanishvili (ყაფლანიშვილი), and Jambakur(ian)-Orbeliani (ჯამბაკურ[იან]-ორბელიანი). They were prominent in Georgia's politics, culture, and science; remained so under the Russian rule in the 19th century – when most of the Orbeliani lines were received among the princely nobility (knyaz) of the Russian Empire – and into the 20th century.
