Družmirje (pronounced [dɾuˈʒmiːɾjɛ], German: Schmersdorf[2]) is a settlement in the Municipality of Šoštanj in northern Slovenia.

[3] Družmirje was attested in historical sources as Tresimir in 1309 (and as Stresimir in 1311, Smerstorf in 1318, and Smersdorf in 1424).

The Slovenian name Družmirje is probably a clipped form of *Družimir′e selo 'Družimirъ's village', referring to an early inhabitant of the place.

They contain the remains of Slovene, Croatian, and German civilians that were murdered on the Gorica Ridge northeast of the town in late May 1945 as they were fleeing to Carinthia.

[5] The second site encompasses three separate burial places in the Lep Thicket (Lepova gošča).
