Barbara Urszula Sanguszko, née Dunin was a Polish noblewoman, poet, translator, and moralist during the Enlightenment in Poland. She organised and hosted a salon in Poddębice, where the gathering of intellectuals, artists and politicians was modelled after French 18th-century salons. Sanguszko was known for her piety and philanthropy. She was the third wife of the much older magnate and Grand Marshal of Lithuania, Duke Paweł Karol Sanguszko (1680–1750).
