FK Mladi Radnik was formed in 1926 and it was initially named SK Radnički.

In the spring of 1927, SK Radnički were officially included in the football league of Požarevac.

Already under the name Mladi radnik the club joined the Football Association of Yugoslavia and started competing in 1928 in the Braničevo-podunavska regional League.

After finishing among top places during the following three seasons, in the 2007–08 season they finished top of the league, thus starting an impressive ascension that will make them climb two levels in two years culminating in promotion to the Serbian SuperLiga.
