Inner Carniola (Slovene: Notranjska pronounced [ˈnòːtɾanska]; German: Innerkrain) is a traditional region of Slovenia, the southwestern part of the larger Carniola region. It comprises the Hrušica karst plateau up to Postojna Gate, bordering the Slovenian Littoral (the Gorizia region) in the west. Its administrative and economic center of the region is Postojna, and other minor centers include Vrhnika, Logatec, Cerknica, Pivka, and Ilirska Bistrica.

The Postojna Gate, less often the Postojna Gap (Slovene: Postojnska vrata), named after the local town of Postojna, is a major mountain pass of the Dinaric Alps. It lies in southwestern Slovenia, between the Hrušica Plateau to the north and the Javornik Hills to the south, at an elevation of 610 metres (2,000 ft). It formed due to tectonic subsidence and fluvial erosion by the Pivka River, which in the Pliocene flew superficially in this section. The terrain is significantly karstified. This relatively wide pass enables for the easiest passage from northeastern Italy and northwestern Adriatic Sea to the Pannonian Plain, and had a very important strategic role in the past. Today, a rail line and the Slovenian A1 freeway traverse it.

Logatec (pronounced [lɔˈɡáːtəts] ; German: Loitsch, Italian: Longatico) is a town in Slovenia. It is the seat of the Municipality of Logatec. It is located roughly in the centre of Inner Carniola, between the capital Ljubljana and Postojna. The town of Logatec has seen rapid industrial development and immigration since the completion of the nearby A1 motorway to the coast.
