Founded in 1919, the club participated in the regional leagues during its early stages. They achieved their first notable success by defeating Dinamo Zagreb 3–1 in the first round of the 1973 Yugoslav Cup. The club also competed in the Yugoslav Second League for three seasons between 1981 and 1984.[1][2]
On 26 October 2005, the club made one of its greatest achievements in its history by eliminating Partizan away in the 2005–06 Serbia and Montenegro Cup round of 16. They won 5–4 on penalties after a 1–1 draw in regular time.[4] The club was eventually knocked out of the competition in the quarter-final after losing 2–0 away to Radnički Niš.[5]
In the 2008–09 season, the club finished second in the Serbian League East, subsequently losing 5–4 on penalties to Teleoptik (after two 1–1 draws) in the promotion play-offs.[6] They were finally promoted to the Serbian First League after winning the 2011–12 Serbian League East title.[7] The club spent two seasons in the second tier of Serbian football, before being relegated back to the Serbian League East in 2014.[8]
After finishing second from the bottom in the 2017–18 Serbian League East, the club got relegated to the fourth tier and was supposed to play in the Zone League East.[9] However, they were unable to compete due to financial reasons, causing them to go inactive.[10] Simultaneously, the Zaječar District League champions and the Zone League East newcomers, FK Radnički Lubnica was relocated to Zaječar and renamed to FK Timok 1919, becoming FK Timok's de facto successor.[9][10]
The club's main supporters group is known as Otrovi (The Poisons).[11] They were founded in 1998, celebrating their 10-year anniversary in a Serbian League East fixture with Župa Aleksandrovac on 15 November 2008. The group is traditionally situated in the east stand of the stadium.
