Soko Grad (Serbian Cyrillic: Соко Град), also known as Sokolac, is a medieval city and fortress 2 km east of the spa town of Sokobanja, Serbia.

The fortress was declared a Monument of Culture of Great Importance in 1982, and it is protected by Republic of Serbia.

[1] The fortress was founded in the 6th century during the reign of Eastern Roman Emperor Justinian I, to prevent incursions of Pannonian Avars and Slavs into Balkan peninsula.

In 1172, it was occupied by Stefan Nemanja and became part of the medieval Serbian state.

During the subsequent development in Serbian state, the fortress expanded around the citadel and spread lower down the rock.
