Pacowie (Polish: Pacowie, Lithuanian: Pacai, Belarusian: Па́цы) was one of the most influential noble families in the Grand Duchy of Lithuania during the era of the Polish-Lithuanian Commonwealth. Numerous high-ranking officials of the Commonwealth came from their ranks. Their coat of arms was Gozdawa.
The family's ancestor Kimantas was mentioned in the privilege of 1388 issued by Grand Duke of Lithuania Vytautas the Great as Kymunt. The estate of the family in proximity of Grodno was mentioned in the road description, charted by the Teutonic Knights, as Kymundsdorf. Kimantas and his son Daukša (Dowkszewicz) were among the signatories of the Union of Vilnius and Radom of 1401. Daukša's son Pac is considered the first member of the family; his ancestors took his first name as their family name, beginning with his son Jerzy Pac (d. 1505/6).
Their lands were concentrated in the southern Lithuania propria, around the county of Jewzno. The family sponsored the construction of several notable examples of Baroque architecture in Lithuania; the most significant of these, St Peter and St Paul's Church in Vilnius and the Monastery of Pažaislis, were commissioned by family members.
In 1753, following a visit to the Pazzi household in Florence, Stefan Pac advanced the theory that the two families were related. The Pacs later dedicated a church to Magdalena de Pazzi. The supposed ancestry was mentioned by 19th century authors, including Balzac.
The family's influence was overwhelmed in the late 17th century by that of the Sapiehas. Michał Kazimierz Pac (1624–1682) was a Grand Hetman of Lithuania and Voivode of Wilno, Krzysztof Zygmunt Pac (1621–1684), Grand Chancellor of Lithuania, Mikołaj Stefan Pac (?-1684), voivode of Trakai and bishop of Vilnius, and Kazmierz Pac (?-1695), bishop of Samogitia. During their adulthood, in late 17th century, they exerted major influence on the politics of the Grand Duchy. After their childless deaths, the Pac family was weakened, and much of their influence passed to others, primarily the Sapiehas. The last notable member of the Pac family was Ludwik Michał Pac (1778–1835), who fought in the November Uprising. After its failure, with his estates confiscated by the Russians, he emigrated to France.
