Adam Stanisław Naruszewicz (Lithuanian: Adomas Naruševičius; 20 October 1733 – 8 July 1796) was a Polish-Lithuanian nobleman, poet, historian, dramatist, translator, publicist, Jesuit and Roman Catholic bishop.

Naruszewicz joined the Jesuit Order on 14 August 1748, and shortly afterward he began studying and from 1753 lecturing in grammar at the Vilnius University.

[2]: 555 [3]: 20  During his time in Western Europe he visited Germany, Italy and Spain and met the Polish Queen of France, Marie Leszczyńska, during an audience at Versailles.

[2]: 555 [3]: 20  He was the editor of the Zabawy Przyjemne i Pożyteczne [pl]—the first Polish literary magazine, published in the years 1770–1777, and a prominent regular at the artistic gatherings, known as the Thursday Lunches, hosted by the king.

[2]: 557, 559 From 1781 to 1786 he was a member of the Permanent Council, the highest administrative authority in the Polish–Lithuanian Commonwealth, and also held the court rank of Great Lithuanian Scribe.

[2]: 559  As a member of the Senate of Polish-Lithuanian Commonwealth he participated in the Great Sejm, aiding Poniatowski's faction's attempts to reform the country.

[1] Naruszewicz was a prolific writer (in both Polish and Latin), beginning his literary career in the late 1740s, with his first published work, a poem dedicated to Jan Mikołaj Chodkiewicz, debuting in 1756,[4]: 7–8  followed by his first research pamphlet a year later.

[3]: 19  He wrote odes, idylls, satires, fairy tales, epigrams, and rococo poems; many of those were praising Poniatowski, although those panegyric works are rarely considered his best.

[2]: 557 [3]: 21–23  His historical research culminated in the seven volumes of Historia narodu polskiego ("History of the Polish Nation"), mostly written in the years 1776–1779 and published in the subsequent decades.

[2]: 560  His literary work has been described by Wolskaand Platt as fitting in the spirit of The Enlightenment, although formally—through their form and language—still displaying many similarities to the styles of the previous era (baroque, classicism, sentimentalism and rococo).

[2]: 560 [3]: 33  Just like his literary work, his historical research and writings have been influenced by the philosophy of Enlightenment, this is visible both in his methodology and philosophy (adhering to concepts such as didacticism, empiricism, humanitarianism, pragmatism, scepticism about tradition, secularism, and utilitarianism), his vernacular writing style, and his goals, such as his emphasis on studying domestic politics, endorsing a strong monarchy, and a pride in national accomplishments (including his support for the usage of Polish language in literature).

[3]: 18, 21 John D. Stanley praised him for his "enormous respect for truth", visible in his methodology, full of critical analysis - including discussion of contradictory accounts, and extensive and detailed references to sources.
