Gmajna () is a dispersed settlement in the City Municipality of Slovenj Gradec in northern Slovenia. It lies in the hills northwest of the town of Slovenj Gradec. The area is part of the traditional region of Styria. The entire municipality is now included in the Carinthia Statistical Region.
The name Gmajna means 'commons', referring to land that was jointly owned and used by the village community. The Slovenian common noun gmajna is a borrowing from Middle High German gemeine, with the same meaning, and is found in other Slovene toponyms such as Gmajna near Krà ¡ko as well as in the diminutive form Gmajnica.
Gmajna is the site of an unmarked grave associated with the Second World War. The SveteÃÂ Woods Grave () is located next to an elder tree in the woods south of the house at Bukovska Vas no. 18. It contains the remains of a Croatian soldier.
