Słupsk shares about three-quarters of its boundaries with the rural district called Gmina Słupsk, of which Słupsk is the administrative seat (although it is not part of the district). The city's other neighbouring district is Gmina Kobylnica, to the south-west. The Słupsk Special Economic Zone is not entirely contained within the city limits: a portion of it lies within Gmina Słupsk, while some smaller areas are at quite a distance from Słupsk (Debrzno), or even in another voivodeship (Koszalin, Szczecinek, Wałcz).
