Princess Gryzelda Konstancja Wiśniowiecka (née Zamoyska of clan Jelita; 27 April 1623 – 17 April 1672) was a Polish noblewoman, known as the mother of King Michał Korybut Wiśniowiecki.

Prince Jeremi Michał Korybut Wiśniowiecki, nicknamed Hammer on the Cossacks (Polish: Młot na Kozaków), was a notable member of the aristocracy of the Polish–Lithuanian Commonwealth, Prince of Vyshnivets, Lubny and Khorol in the Crown of the Kingdom of Poland and the father of the future King of Poland, Michael I.

A notable magnate and military commander with Ruthenian and Moldavian origin, Wiśniowiecki was heir of one of the biggest fortunes of the state and rose to several notable dignities, including the position of voivode of the Ruthenian Voivodship (today Poland and Ukraine) in 1646. His conversion from Eastern Orthodoxy to Roman Catholicism caused much dissent in Ruthenian lands (part of the Polish–Lithuanian Commonwealth). Wiśniowiecki was a successful military leader as well as one of the wealthiest magnates of Poland, ruling over lands inhabited by 230,000 people.

A charismatic leader and skilled military commander, Wiśniowiecki became famous for his decisive and frequently cruel actions during the Khmelnytsky Uprising, in the course of which he achieved several victories against rebellious Zaporozhian Cossacks and engaged in a campaign of terror against their perceived supporters around Ukraine. He died during one of anti-Cossack campaigns in 1651. His son Michał Korybut Wiśniowiecki would later become King of Poland and Grand Duke of Lithuania.
