Mount Prestreljenik () is a mountain in the western range of the Julian Alps, in the Tolmin region of Slovenia on the Italian-Slovenian border. It is the second-highest peak in the central part of the Kanin group. Prestreljenik is known for the Window (Okno), an erosion-arch feature located on its western ridge. This aperture is the source of both of the mountain's local endonyms; Prestreljenik means 'shot-through' in Slovene, and Forato is Italian for 'pierced'
