Paczków [ˈpat͡ʂkuf] (German: Patschkau; Silesian: Paczkōw) is a town in Nysa County, Opole Voivodeship, in southern Poland, with 7,460 inhabitants (2019).

[6] The old town and its medieval fortifications are listed as one of Poland's official national Historic Monuments (Pomnik historii), as designated November 13, 2012.

[7] Paczków, mentioned in medieval documents under the Latinized Old Polish names Paczkaw (Liber fundationis episcopatus Vratislaviensis) and Patzkow (Book of Henryków), quickly grew, becoming not only a market town, but also a stronghold, guarding southwestern borders of the ecclesiastical Duchy of Nysa of fragmented Poland.

The new town received several privileges, such as the right to brew beer, and its early inhabitants were mostly craftsmen, such as bakers, butchers and shoemakers.

In the Late Middle Ages and subsequent periods, Paczków shared the stormy fate of other towns of Silesia, with frequent disasters, such as hunger (1325), floods (1333, 1501, 1539, 1560, 1598, 1602), fires (1565, 1634), as well as epidemics - Black Death (1349), and cholera (1603–1607, 1633).

In 1526 Paczków, under the Germanized name Patschkau, together with the Duchy of Nysa, passed under the suzerainty of the Austrian Habsburg dynasty.

The unique Gothic church, which is made of stone and bricks displays a renaissance attic, and its mighty structure has been incorporated into the town's fortifications.

According to a legend, a Tatar warrior (see Mongol invasion of Poland) was thrown into the well, after he had captured the daughter of a wealthy inhabitant of Paczków.

[14] To the west of Paczków, the Paczkowski Lake, while predominantly performing the role of protecting the locality from flooding, is also home to a small fishing industry.

Apart from food production, Paczków is home to numerous heavy industry complexes, including the "EMSTEEL" steel plant by Robotnicza Street (ul.
