Russians in Armenia are ethnic Russians living in Armenia, where they make up the second largest minority. In the 2022 census, there were 14,074 Russians counted, making up about 0.5% of the whole population of Armenia. A reportage in November 2022 says that more than 300,000 Russians moved to Armenia since the beginning of Russo-Ukainian war.

Bilateral relations between modern-day Armenia and the Russian Federation were established on 3 April 1992, though Russia has been an important actor in Armenia since the early 19th century. The two countries' historic relationship has its roots in the Russo-Persian War of 1826 to 1828 between the Russian Empire and Qajar Persia after which Eastern Armenia was ceded to Russia. Moreover, Russia was viewed as a protector of the Christian subjects in the Ottoman Empire, including the Armenians.
