Mislinja (pronounced [miˈsliːnja]; German: Missling[2]) is a settlement in northern Slovenia.

The Mislinja Gorge is petrographically diverse, consisting of schist, diaphorite, quartzite, gneiss, amphibolite, tonalite, and other minerals.

[2] During the Middle Ages, guards responsible for the provincial border between Carinthia and Styria were stationed in villages in the area; the hamlet of Straže (literally, 'guards') to the northwest reflects this history.

The landowner Arthur Perger (1852–1930) built a 9 km electric railroad through the Mislinja Gorge northeast of the settlement in 1902.

Large-scale arrests took place in January 1942, and some of Mislinja's residents fled to Lower Carniola.

A bunker that provided care for wounded Partisans and storage was established in the Križnik Woods in May 1944.

Both are former anti-tank trenches and contain the remains of a large number of Ustaša soldiers and Croatian civilians.

One is dedicated to Saint Leonard and was built in the mid-17th century on the site of an earlier church first mentioned in written documents dating to 1476.
