Prestreljenik is a 2,499-meter mountain in the western range of the Julian Alps. The summit of the mountain lies on the Italian–Slovenian border, which runs along the Kanin group ridge in the area. The mountain's southern and northern slopes lie in the Slovenian municipality of Tolmin and the Italian commune of Udine, respectively.
The second-highest peak of the central part of the Kanin group, Prestreljenik is located about 2.5 km west of High Kanin / Canin Alto. It is best known for the "Window", an erosion-arch feature located on its western ridge. This aperture is the source of both of the mountain's local endonyms, Prestreljenik and Forato.
