Kaçanik (Albanian definite form: Kaçaniku) or Kačanik (Serbian Cyrillic: Качаник, pronounced [kâtʃaniːk]), is a town and municipality located in the Ferizaj District of southern Kosovo.

[2][3] The region of Kaçanik was one of the pathways, which were employed during Central European (akin to the Lusatian culture) migrations in the southern Balkans between 1200 and 1150 BCE.

[4] Roman era monuments include an altar that dates to 158–9 CE and is dedicated to a deity named Andinus (Deo Andino).

[7][8] Kaçanik was founded by Koca Sinan Pasha, who erected a tower, the town mosque which exists even today, a public kitchen for the poor (imaret), a school near the mosque, two hane (inns similar to caravanserais), one Turkish bath (hammam), the town fortress called Llanishta Fortress and a few mills on the Lepenci river.

In 1990, after the suspension of Kosovo's autonomy, the members of the Kosovan assembly gathered in the town and adopted the Kaçanik Constitution, based on which the Republic of Kosova was proclaimed in 1991.

Kaçanik has an old tradition in private manufactures, especially when it comes to the production of calcareous stone, wood for construction purposes and other services and artisan skills.
