Kočna (pronounced as /sl/) is a settlement in the Municipality of Jesenice in the Upper Carniola region of Slovenia.
Kočna is a relatively common toponym in Slovenia. It is derived from the Slovene common noun kočna 'cirque' and originally refers to a local geographical feature.[2]
Kočna is the site of a mass grave from the period immediately after the Second World War. The Kočna Mass Grave (sl|Grobišče Kočna), also known as the Poljane nad Jesenicami Mass Grave (Slovenian: Grobišče Poljane nad Jesenicami), is located southeast of the settlement, a few dozen meters from a dirt road. It is a visibly sunken area measuring 4mx1.5mm (13feetx04.9feetm) and it contains the remains of up to 40 German prisoners of war murdered on 7 or 10 May 1945. One of the intended victims was able to escape.[3]
Excavations in 1982 at the Jamnik Rock Shelter (sl|Jamnikov spodmol) east of the settlement revealed artifacts from the Mesolithic era. The finds included a bone harpoon blade.[4]
