The Gradascica is a river in Slovenia. The river is 33 km (21 mi) long. It begins in Polhov Gradec at the confluence of Little Creek (Slovene: Mala Voda) and Big Bozna Creek. Near Vrhovci it is joined by Horjulscica Creek (a.k.a. Horjulka Creek). Not far past Bokalce most of the stream is split off into the Mali Graben Canal and the rest continues as the Gradascica (also known as the Mestna Gradascica 'Town Gradascica').
