The Stroganovs or Strogonovs (), French spelling: Stroganoff, were a family of highly successful Russian merchants, industrialists, landowners, and statesmen. From the time of Ivan the Terrible () they were the richest businessmen in the Tsardom of Russia. They financed the Russian conquest of Siberia (1580 onwards) and Prince Pozharsky's 1612 reconquest of Moscow from the Poles. The Stroganov School of icon-painting (late 16th and 17th centuries) takes its name from them. The most recent common ancestor of the family was Fyodor Lukich Stroganov (died 1497), a salt industrialist. His elder son, Vladimir, became the founder of a branch whose members eventually became state peasants; this lineage continues. The lineage from Fyodor Lukich Stroganov's youngest son, Anikey (1488–1570), died out in 1923. Anikey's descendants became members of the high Russian nobility under the first Romanovs (tsars from 1613 onwards).
