The Morsztyn family (historical variants: Morrinstein, Mornsteyn, Morstin) is a prominent Polish noble family that use the Leliwa coat of arms. The family achieved great prominence within the Polish–Lithuanian Commonwealth, producing several notable figures in Polish politics, diplomacy, and literature, most notably the prominent Baroque poets Jan Andrzej Morsztyn, Zbigniew Morsztyn, and Hieronim Morsztyn. In 1822, the branch of the Counts Morsztyn also received official recognition of the title of Graf in the Austrian Empire by Francis I, Emperor of Austria.
When the Second Polish Republic adopted its constitution in 1921, it officially abolished the noble class, stripped away all hereditary titles, and ended noble privileges. Therefore, Morsztyn became a standard Polish surname. Archaic feminine forms are Morsztynowa (by husband) and Morsztynówna (by father); they still can be used colloquially.
