Mrzlava Vas (pronounced [məɾˈzlaːʋa ˈʋaːs]; Slovene: Mrzlava vas) is a village in the hills above the right bank of the Krka River, in the Municipality of Brežice in eastern Slovenia. The area is part of the traditional region of Lower Carniola. It is now included in the Lower Sava Statistical Region. The village church, built on an isolated location south of the main settlement, is dedicated to the Holy Spirit and belongs to the Parish of Čatež ob Savi. It was originally a medieval building, but was extensively rebuilt in 1864 when the belfry was also added.
