Russian Americans are Americans of full or partial Russian ancestry. The term can apply to recent Russian immigrants to the United States, as well as to those who settled in the 19th century Russian possessions in northwestern America. Russian Americans comprise the largest Eastern European and East Slavic population in the U.S., the second-largest Slavic population generally, the nineteenth-largest ancestry group overall, and the eleventh-largest from Europe.
