The House of Poniatowski (plural: Poniatowscy) is a prominent Polish family that was part of the nobility of Poland. A member of this family, Stanisław Poniatowski, was elected as King of Poland and reigned from 1764 until his abdication in 1795. Since Polish adjectives have different forms for the genders, Poniatowska is the equivalent name for a female member of this family.


The Poniatowski family became most prominent in the late 18th century and 19th century. In three generations, the family rose from the rank of gentry to that of senator and then to royalty (in an elective monarchy).

The first information about the family dates back to the end of the 15th century, when they appeared in Poniatowa, 40 km west from Lublin in about 1446. Their family name derives from that place name. Poniatowa was the residence of several branches of the Poniatowski family: Tłuk, Jarasz and Ciołek.

According to the family's history, the family had ties with the Italian nobility: Giuseppe Salinguerra, a member of the Italian family of Torelli, settled in Poland about the middle of the 17th century, and there assumed the name of Poniatowski from the estate of Poniatow, belonging to his wife, who was the daughter of Albert Poniatowski and Anna Leszczyńska.
