Radnik Surdulica

The club was founded as Surdulički sportski klub (SSK) in 1926 on the initiative of Gradimir Antić, a local shoemaker, who brought the first football ball to Surdulica. They stopped operating with the onset of World War II and Axis occupation of Serbia. In 1946, the club was reestablished as FK Polet on the initiative of Borivoje Milenković and Božidar Stanković. They subsequently changed their name to FK Hidrovlasina in 1950. Later the same year, the club merged with FK Molidben from Belo Polje and was named FK Radnik.

In July 2008, the club merged with FK Železničar from Vranjska Banja, taking its spot in the Serbian League East. They spent the next five seasons in the third tier of Serbian football. After winning the title in 2013, the club was promoted to the Serbian First League. They spent the next two seasons in the second tier before placing first in the 2014–15 Serbian First League and earning promotion to the Serbian SuperLiga for the first time in their history. In the 2020–21 season, the club achieved its highest ever league finish of sixth place and also reached the semi-finals of the national cup.
