Dedni Dol (in Slovenian pronounced as /ˈdeːdni ˈdɔu̯/; German: Dedendol[2]) is a settlement northwest of Višnja Gora in the Municipality of Ivančna Gorica in central Slovenia. The area is part of the historical region of Lower Carniola. The municipality is now included in the Central Slovenia Statistical Region.[3]
