The Mislinja (in Slovenian pronounced as /miˈsliːnja/) is a river in the northern part of Slovenia. It is 36abbr=on long. It flows through Mislinja and Slovenj Gradec and empties from the right into the Meža River north of the village of Otiški Vrh near Dravograd, only a couple hundred meters before the Meža joins the Drava River.
The name Mislinja is derived from the phrase *Myslin'a (voda) (literally, 'Myslinъ's creek'), thus referring to a person or people living along the watercourse. The hypocorism *Myslinъ is derived from the personal name *Myslь. The town of Mislinja is named after the river.[1]
