Kutaisi (/kuːˈtaɪsiː/ koo-TY-see; Georgian: ქუთაისი pronounced [ˈkʰut̪ʰais̪i] ^ⓘ) is a city in the Imereti region of the Republic of Georgia. One of the oldest continuously inhabited cities in the world, it is the 3rd-largest city in Georgia after Tbilisi and Batumi with a population of 123,000 as of 2025. It lies 221 kilometres (137 miles) west of Tbilisi, on the Rioni River, and is the capital of Imereti.

Historically one of the major cities of Georgia, it served as the political center of Colchis in the Middle Ages as the capital of the Kingdom of Abkhazia and Kingdom of Georgia and later as the capital of the Kingdom of Imereti. From October 2012 to December 2018, Kutaisi was the seat of the Parliament of Georgia as an effort to decentralize the Georgian government.

Archaeological evidence indicates that the city functioned as the capital of the Colchis in the sixth to fifth centuries BC. It is believed that, in Argonautica, a Greek epic poem about Jason and the Argonauts and their journey to Colchis, author Apollonius Rhodius considered Kutaisi their final destination as well as the residence of King Aeëtes.

Later, it was the capital of the kingdom of Lazica until being occupied briefly by the Arabs. An Arab invasion into western Georgia was repelled by Abkhazians jointly with Lazic and Iberian allies in 736, towards c.786, Leon II won his full independence from the Byzantine Empire and transferred his capital to Kutaisi, thus unifying Lazica and Abasgia via a dynastic union. The latter led the unification of the Georgian monarchy in the 11th century.

From 1008 to 1122, Kutaisi served as the capital of the Kingdom of Georgia, and, from the 15th century until 1810, it was the capital of the Kingdom of Imereti. In 1508, the city was conquered by Selim I, who was the son of Bayezid II, the sultan of the Ottoman Empire.

During the 17th century, Imeretian kings made many appeals to the Russian Empire to help them in their struggle for independence from the Ottomans. All these appeals were ignored as Russia did not want to spoil relations with the Ottomans. Only in the reign of Catherine the Great, in 1768, were troops of general Gottlieb Heinrich Totleben sent to join the forces of King Heraclius II of Georgia, who hoped to reconquer the Ottoman-held southern Georgian lands, with Russian help. Totleben helped King Solomon I of Imereti to recover his capital, Kutaisi, on August 6, 1770.

Finally, the Russian-Turkish wars ended in 1810 with the annexation of the Imeretian Kingdom by the Russian Empire. The city was the administrative capital of the Kutaisi uezd and the larger Kutaisi Governorate, which included much of west Georgia.

In March 1879, the city was the site of a blood libel trial that attracted attention all over the Russian Empire. Nine Georgian Jews from Sachkhere were falsely accused of killing a Christian girl and using her blood for allegedly Jewish religious purposes. The trial took place at the Kutaisi Circuit Court, which had been established in 1868 as one of several new courts in the Caucasus created by Tsar Alexander II.'s Judicial Reform. After a ten-day trial, with nearly 70 witnesses, the nine defendants were acquitted as the defense lawyers Petr Aleksandrov, Lev Kupernik and Moisei Kikodze convinced the judges that the accusations against the Jewish men were mostly based on false testimony.
