Prestreljenik, Mountain summit in the Julian Alps, Italy and Slovenia

Prestreljenik is a 2,499-meter mountain in the western Julian Alps, on the Italian–Slovenian border. Its western ridge holds the "Window" (Okno), an erosion arch that gives the peak both its Slovene name, meaning "shot-through", and its Italian name, Monte Forato, meaning "pierced". The summit is the second-highest of the central Kanin group, about 2.5 km west of High Kanin.

Prestreljenik lies on the Italian–Slovenian border along the Kanin group ridge, with its southern slopes in the Slovenian municipality of Tolmin and its northern slopes in the Italian province of Udine. The mountain's name, Slovene for "shot-through" and Italian for "pierced", refers to the Okno, an erosion arch on its western ridge. The peak is the second-highest of the central Kanin group, about 2.5 km west of High Kanin.

The mountain's two local names both describe its central feature: Prestreljenik means "shot-through" in Slovene and Monte Forato means "pierced" in Italian, both referring to the Okno (Window) arch on the western ridge. The summit sits on the Italian–Slovenian border, with the northern slope in the Italian commune of Udine and the southern slope in the Slovenian municipality of Tolmin.

Reaching the summit requires proper mountain hiking gear and experience with steep terrain. Check weather conditions before setting out, as conditions can change rapidly at high elevations.

The mountain's Slovene name, Prestreljenik, means "shot through", and the Italian name Monte Forato means "pierced"; both refer to the Okno (Window), an erosion arch on the western ridge that gives the peak its name in both languages.
