Mass graves in Ljubljana were created in Ljubljana, Slovenia during and after the Second World War. The Commission on Concealed Mass Graves in Slovenia has registered five known mass graves in the city itself and an additional 15 in the City Municipality of Ljubljana.
Except for the Orel Peak Mass Grave, which is a former wartime Home Guard cemetery, all of the concealed mass graves in Ljubljana were created in the immediate aftermath of the Second World War, after British forces repatriated Home Guard soldiers that had fled to Austria to Yugoslavia from camps in Bleiburg, Lavamund, Rosenbach, Viktring (a district of Klagenfurt), and elsewhere. Many of the returnees were held at the St. Stanislaus Institute in the former village of à  entvid, just outside Ljubljana, which was used as a prison by the Partisans. Some died in à  entvid, but most were transported elsewhere and murdered.
Five mass graves registered by the Commission on Concealed Mass Graves in Slovenia are located inside the city limits:
The Society for the Regulation of Concealed Graves () installed a pair of plaques on the à  entvid cemetery wall facing the graves in 2002. They read: "The victims of violence from the Partisan collection center in à  entvid (MayâÂÂSeptember 1945) lie and await the resurrection behind this wall. In memory of the victims, a warning to the living," and quote the Book of Wisdom (3:4âÂÂ5): "For though they be punished in the sight of men, yet is their hope full of immortality. And having been a little chastised, they shall be greatly rewarded: for God proved them, and found them worthy for himself."
Other victims from the prison in à  entvid were killed outside Ljubljana, in Glaà ¾uta, Golo, Onek, and Setnica.
An additional mass grave in the city is likely located in Dobrunje, but has not been registered by the commission. The memorial site at Saint UlrichâÂÂs Church is believed to contain the remains of people liquidated by the Partisans during or after the war, including the "à  entpavel victims" ()âÂÂeight men abducted by Yugoslav military police (KNOJ) from the village of à  entpavel on 4 July 1945 and murdered.
Fifteen additional mass graves are located in the City Municipality of Ljubljana outside the Ljubljana city limits. There are four graves in Pance and 11 graves in Selo pri Pancah.
