Žabja Vas (pronounced [ˈʒaːbja ˈʋaːs], Slovene: Žabja vas, in older sources also Žabja Luža, German: Froschdorf) is a former village in southeastern Slovenia in the Municipality of Novo Mesto. It is now part of the city of Novo Mesto. It is part of the traditional region of Lower Carniola and is now included in the Southeast Slovenia Statistical Region.

Žabja Vas lies southeast of the town center of Novo Mesto, along both sides of the road to Kostanjevica na Krki. The Gotna Vas Woods (Slovene: Gotenski boršt) stand southeast of Žabja Vas.

The name Žabja vas means 'frog village'. There are several places with this name in Slovenia (e.g., Žabja Vas in the Municipality of Gorenja Vas–Poljane), as well as other names based on the common noun žaba 'frog', such as Žabnica, Žabče, and Žablje. Such names originally referred to a wetland with frogs and then later to a settlement built next to it. The older name of the settlement, Žabja Luža, means 'frog pond'.
