Prince Yuri Yurievich Trubetskoy (April 20, 1668, September 8, 1739) was a Russian statesman, senator, and actual privy councilor. He was the younger of the two Trubetskoy princes of the late 17th century and a common ancestor of all members of the family who lived after 1750.

Yuri was the second son of boyar Y. P. Trubetskoy and the nephew of the "great Golitsyn." He began his court career as a chamber squire under Tsars Fyodor Alexeyevich and Peter I. Later, he joined Peter's toy army and by 1694, during the Kozhukhov maneuvers, he was already serving as a captain in the Preobrazhensky regiment.

In 1700, Yuri Yurievich unsuccessfully negotiated in Berlin with the Prussian Elector about joining the Northern Alliance. In 1710, he accompanied Tsarevich Alexei Petrovich to Dresden for his education. During this period, he visited many countries and learned Italian, which he used to communicate in Moscow with the Dutchman de Bruyn for a long time.

While his older brother Ivan Yurievich was in Swedish captivity for 18 years, Yuri advanced through several ranks in military service and became a brigadier in March 1719. The family chronicle notes his contributions to the capture of Derbent by Russian troops in 1722. He also participated in the construction of the Peter and Paul Fortress, where the Trubetskoy Bastion was named in his honor.

In 1720, Yuri was appointed president of the Magistrate, the highest body of city administration in Russia, and Catherine I awarded him the rank of general-poruchik. In 1727, he headed the newly formed Belgorod Governorate.

After the ascension of Anna Ioannovna to the throne, Prince Trubetskoy became a senator (March 4, 1730) and soon was honored with the title of actual privy councilor (April 28 of the same year). He passed away in 1739 and was buried in the Alexander Nevsky Lavra.
