In 1921 the club was founded under the name SOKO in Belgrade's suburb Bežanija and at that time it did not fall neither under Belgrade nor Zemun football leagues. Later the club changes its name to BSK. At that time the club only managed to play friendly matches. During World War II under German occupation, Bežanija joined a Croatian NDH league and renamed HSK. In the club, despite everything, all players were Serbs. After the war in 1946 the club changes its name to FK Jedinstvo. That year the club for the first time starts competing in the Srem league and becomes a member of the Novi Sadfootball association. Till 1952 the club was competing in the regional Srem League. In 1952 the club transfers to the Belgrade football association, and since then all the results have been written down. That same year the club forms its youth club that begin competing in the second youth league. At the beginning of the 1955–56 season FK Jedinstvo changes its name to the current FK Bežanija. Since 1953 to 1989 season the club competes in lower league, and promotions and relegations were regular. In the season 1988–89 the club is promoted to the Belgrade Zone League for the first time in its history. The next season recorded further success and the club qualified to the Serbian League. In 1992–93 the club is promoted with even more success and moves on to the Republic zone league Belgrade. The biggest club success was in 1999-00 when the club was promoted once more to the First league in Serbia, but was relegated one season later. FK Bežanija gives much attention to its youth system which keep getting better and better results. This was born out when Bežanija's young squad finished 4th in the 2006–07 SuperLiga and were thus entered into the qualifying rounds of the 2007-08 UEFA Cup. Already in the recent history it is worth to mention that by the year 2010, the club has managed to participate twice in the national top league, the Serbian SuperLiga, having played in the seasons 2006–07 and 2007–08. In 2019, IELTSPodcast, an online school owned by Ben Worthington sponsored the club.
