Monte San Martino, mountain summit in Friuli-Venezia Giulia, Italy

Monte San Martino is a mountain summit in northeastern Italy reaching approximately 987 meters, situated in the Friuli-Venezia Giulia region. The peak offers sweeping views across surrounding valleys and adjacent mountains.

The mountain's strategic position between two valleys and near a pass made it a lookout point since ancient times. On 21–22 April 1848 local volunteers defended the homeland's borders there against Austro-Hungarian troops coming from the Luico pass toward insurgent Udine. A stone marker near the church recalls the event.

Every third Sunday of September a Slovenian kujtarinca fair is held around the small Romanesque church on the summit, drawing worshippers from distant villages. The church is dedicated to Saint Martin, who gives the mountain its name, Svet Martin in Slovene.

The usual approach starts at Passo del Priavelo (663 m), reached from Grimacco; a path and a recently repaired mule track climb through chestnut woods to the 987 m summit. The CAI trail no. 761 runs from Scrutto via Clastra and Passo San Martino to Bocchetta di Topolò, about 5 hours. Trail no. 7 of the Sentieri di pace leaves Clodig for the summit, Topolò and back: 13 km, 734 m of ascent, easy on foot, medium-hard by mountain bike.

In 1998 a hoard of nine tools from late antiquity was found on the mountain, showing the site was used long before the church. Two cave entrances and a foiba, the Foiba del monte San Martino, open on its slopes.
