Obrežje (pronounced [ɔˈbɾeːʒjɛ]) is a settlement in the Municipality of Radeče in central Slovenia.

It lies on the left bank of the Sava River and is thus part of the traditional region of Lower Styria, rather than Lower Carniola, where the rest of the municipality on the opposite bank of the river belongs.

[2] Obrežje is the site of a mass grave associated with the Second World War.

The bunker is 8 to 10 meters (26 to 33 ft) long and the entrance is now covered by soil.

It contains the remains of an unknown number of Montenegrin Chetnik soldiers.
