Marija Reka (pronounced [maˈɾiːja ˈɾeːka]; German: Maria Riek[2]) is a settlement in the Municipality of Prebold in east-central Slovenia.

The Stergar Quarry (Slovene: Stergarjev kamnolom) operated in Marija Reka from 1936 to 1962.

On April 14, 1942, a Partisan unit destroyed a Gestapo vehicle on the road from Marija Reka to Trbovlje, and the Partisans' Robida printshop operated on the north slope of Mount Reka (Slovene: Reška planina) in the summer of 1943.

The graves contain the remains of about 2,000 civilians from Trbovlje, Hrastnik, Zagorje ob Savi, Laško, Žalec, and the surroundings of Celje, as well as several hundred Croatian civilians and about 100 German prisoners of war.
