Breznica (pronounced [ˈbɾeːznitsa]; German: Bresnitz[2]) is one of ten villages in the Municipality of Žirovnica in the Upper Carniola region of Slovenia.

Most of the village has developed on the slopes of the Reber range, leaving open fields towards the south and east.

Like similar toponyms in Slovenia (e.g., Brezova, Brezovec, Brezovci), it originally referred to the local vegetation.

Construction of the current parish church began in 1819, and its architect was Blasio Zamolo from Gemona, whose signature can be found above the main entrance.

In front of the church stands a monument to those who fell in World War I, designed by the architect Jože Plečnik.
