Stanisława Biskupa i Męczennika, Russian: Орден Святого Станислава), also spelled Stanislas, was a Polish order of knighthood founded in 1765 by King Stanisław August Poniatowski of the Polish–Lithuanian Commonwealth.

[3] The knights were required to pay for donations to poor people and to adhere to various rules of chivalry.

Due to the rising influence of the Russian Empire on Central European affairs, the rules of awarding of the order were broken.

Yet, after the downfall of the November Uprising the Imperial House of Romanov established the Royal and Imperial Order of Saint Stanislaus, incorporating it into the honours system of the Russian Empire in 1832, where it remained officially until the Russian Revolution 1917.

In the Russian version of the badge, the Polish white eagles were replaced with gold Russian double-headed imperial eagles, their wings partially overlapping the arms of the cross and the central medallion bearing the letters "SS" in red on a white enamel background instead of the original image of the saintly bishop, surrounded by a green enamel laural wreath.
