The Principality of Guria (, guriis samtavro) was a historical state in Georgia. Centered on modern-day Guria, a southwestern region in Georgia, it was located between the Black Sea and Lesser Caucasus, and was ruled by a succession of twenty-two princes of the House of Gurieli from the 1460s to 1829. The principality emerged during the process of fragmentation of a unified Kingdom of Georgia. Its boundaries fluctuated in the course of permanent conflicts with neighboring Georgian rulers and Ottoman Empire, and the principality enjoyed various degrees of autonomy until being annexed by Imperial Russia in 1829.
