The Račna Karst Field (pronounced [ˈɾaːtʃna]; Slovene: Radensko polje) is a karst field in the northern edge of the Lower Carniolan karst area, south of Grosuplje, Slovenia. It has rich natural and cultural value. Because of its ecological significance, it is anticipated that a nature park will be established there and that it will be included in the Natura 2000 program.
