Krn is a mountain of the southwestern Julian Alps in northwestern Slovenia. It is the highest mountain of the Krn Mountains. The mountain is located about 50 kilometres from the Adriatic Sea. The Soča River flows west of the peak, and the smaller Lepenjica River northeast and the Tolminka River southwest of it. Krn has a mighty western wall, which can be best seen from Kobarid or Drežnica.
On the southern slope of the mountain lie the small villages of Vrsno, Krn, Drežnica, Drežniške Ravne, and Magozd. On the northern side lies Lake Krn, the largest glacial lake in Slovenia.
