Mislinja is a settlement in northern Slovenia. It is the seat of the Municipality of Mislinja. It lies in the valley of the Mislinja River. The area traditionally belonged to Styria. In 1995 it became part of the newly formed Carinthia Statistical Region.

Mass graves in Slovenia were created in Slovenia as the result of extrajudicial killings during and after the Second World War. These clandestine mass graves are also known as "concealed mass graves" or "silenced mass graves" because their existence was concealed under the communist regime from 1945 to 1990.
