Yury, Yuri, or Yuriy is the East Slavic (Russian: Юрий or Ukrainian: Юрій) form of the masculine given name George; it is derived directly from the Greek form Georgios and related to Polish Jerzy and Czech/Slovak Jiří.
The Slavic form of the name originates with Yuriy Dolgorukiy, Grand Prince of Kiev and founder of Moscow (c. 1099 – 1157), in early accounts recorded as Gyurgi, Dyurgi. Its popularity reflects the veneration of Saint George in the Kievan Rus'. Yaroslav the Wise, great-grandfather of Yuriy Dolgorukiy, was the first Russian ruler whose patron saint was Saint George. The saint is now depicted on the coat of arms of Moscow.
