Bad Lausick (German: [ˈbaːt ˈlaʊzɪk] ⓘ) is a town in the Leipzig district, in Saxony, Germany.

1878 can be considered as the zenith of the lignite mining and lime burning industries, with 36 pits and 20 kilns in Köllsdorf alone.

Construction of the Bügerschule (civic school) for 900 pupils started in 1886, and in 1887 the Leipzig–Geithain railway via Lausick opened.

At this time, there were also 11 lignite mines, five lime kilns, 30 agricultural businesses, 20 bakers, 25 shoemakers, 25 tailors, 17 weavers, 10 butchers and 43 other craftsman's establishments as well as 23 restaurants and inns.

In 1956 a rural department store (Landwarenhaus) opened on the market square, and in 1957 the romanic character of St Kilian church was restored.

A Silbermann organ dating from 1722 and extended by Johann Gottlob Trampeli was installed in the church at the same time.

Former enterprises with state holdings were fully nationalized by that time, in particular the house shoe factory and the mill works.

The silicate works were modernised and expanded between 1979 and 1988, and in 1988 construction of a new town quarter was started as a major public housing project.

The neighbouring villages Steinbach, Beucha, Kleinbeucha, and Stockheim were incorporated into Bad Lausick in 1999.

[11] Further, mostly medium-sized enterprises include the manufacturing of steel furniture and of surgical dressing materials, cleaning contractors, and businesses in engineering construction (namely of pipework and of solar energy plants).

A vocational training establishment is present in the town with the Evangelische Schule für Sozialwesen (Evangelical School for Social Welfare) "Luise Höpfner", founded in 1953.

[12] Deutsche Bläserakademie, an educational institution specialising in wind instrument music and Sächsische Bläserphilharmonie, Germany's only symphonic concert band, are based in Bad Lausick.

[13] Several members of the powerlifting club KSV Bad Lausick e.V., founded in 1982 and organising multiple yearly competitions, have also advanced to the national sports team in this discipline.
