Sokol was a hill-side fortress located near the confluence of the rivers Piva and Tara, today south of the village of Šćepan Polje at the border of Montenegro and Bosnia and Herzegovina. It's also referred to as Sokol grad and Soko.

The fortress was believed to have been mentioned as međurječje lit. 'the place between the rivers' in 10th century sources, and became known as Sokol under the rule of Stjepan Vukčić Kosača in the 15th century. Below the fortress is the Zagrađe Monastery [sr], a monastery of the Serbian Orthodox Church dedicated to St. John the Baptist.
