The Georgian dialects are classified according to their geographic distribution, reflecting a traditional ethnographic subdivision of the Georgian people. Beyond the Western and Eastern categories, some scholars have also suggested a Southern group. These can be further subdivided into five main dialect groups as proposed by Gigineishvili, Topuria, and K'avtaradze (1961):
- Imeretian (Imeruli, იმერული) in Imereti
- Lechkhumian (Lečkhumuri, ლეჩხუმური) in Lechkhumi
- Rachan (Račuli, რაჭული) in Racha
- Megrelian (margaluri, მეგრული ) in Samargalo
The Central dialects, sometimes considered part of the Eastern group, are spoken in central and southern Georgia, and provide the basis for Standard Georgian language.
- Kartlian (Kartluri, ქართლური) in Kartli
- Meskhian (Meskhuri, მესხური) in Meskheti
- Javakhian (Javakhuri, ჯავახური) in Javakheti
This group is spoken by the mountaineers in northeast Georgia.
- Mokhevian (Mokheuri, მოხეური), spoken in Khevi
- Mtiuletian-Gudamaqrian (Mtiulur-Gudamaqruli, მთიულურ-გუდამაყრული) in Mtiuleti and Gudamaqari
- Khevsurian (Khevsuruli, ხევსურული) in Khevsureti
- Pshavian (Pšavuri, ფშავური) in Pshavi
- Tushetian (Tušuri, თუშური) in Tusheti
Two of these dialects, Ingiloan and Fereidanian, are spoken outside Georgia, the former by the indigenous Georgians in northwest Azerbaijan, and the latter by the descendants of the 17th-19th century Georgian deportees and migrants in Iran.
- Kakhetian (Kakhuri, კახური) in Kakheti
- Tianetian (Tianeturi, თიანეთური) in Ertso-Tianeti
- Ingiloan (Ingilouri, ინგილოური) in Saingilo (Azerbaijan)
- Fereydanian (Pereidnuli, ფერეიდნული) in Fereydan (Iran)
- The obsolescent Kizlar-Mozdokian dialect, was spoken in the north central Caucasian areas of Kizlyar and Mozdok by descendants of those Georgians who fled the Ottoman occupation of Georgia in the early 18th century. It was technically a mixture of various Georgian dialects laden with Russian loanwords. Subsequently, the group was largely Russified and the dialect became extinct.
- Judæo-Georgian is a language spoken by the Georgian Jews. Largely Georgian phonetically, morphologically, and syntactically, and mixed Georgian-Hebrew lexically, it is considered by some not to be a distinct language but rather a dialect of Georgian.
