The Imperial Order of Saint Stanislaus is a Russian dynastic order of knighthood founded as Order of the Knights of Saint Stanislaus, Bishop and Martyr in 1765 by King Stanisław II Augustus of the Polish–Lithuanian Commonwealth. In 1831 after the downfall of the November Uprising, the order was incorporated into the Chapter of Russian Orders as part of the honours system of the Russian Empire by Emperor Nicholas I of Russia.
In 1839, the Russian Order of Saint Stanislaus received new statutes, including granting status of nobility on its recipients in all three classes.
