Pajęczno [paˈjɛnt͡ʂnɔ] is a town in Poland, in Łódź Voivodeship, about 40 kilometres (25 miles) north of Częstochowa.

First mentioned in historical sources from 1140, when it was part of Piast-ruled Poland.

[2] When the Germans occupied the town in September 1939, they unleashed a violent attack against the Jewish community, beginning with murder and abuse, then stripping Jews of most of their property, and in 1941, confining them to an overcrowded ghetto.

In 1942, the Germans also expelled 312 Poles, who were deported to a transit camp in nearby Wieluń and then to forced labour in Germany and German-occupied France.

[6] On 14 June 2019 an intoxicated man drove through the town in a T-55 tank and was arrested shortly after.
