Currently, Borac is a part of the Premier League of Bosnia and Herzegovina and plays its home matches at the Banja Luka City Stadium, which has a capacity of 10,030 seats.
The club was founded by a group of football enthusiasts including the writer, activist and People's Hero of Yugoslavia Veselin Masleša, Rudolf "Rudi" Hiter, Savo Novaković, Nikola Pucar, Brane Pucar, Mustafa Softić, Nikola Kuković, Žarko Vranješević, Mile Stefanović and Brane Stefanović among others.
They financed the club believing that by backing and supporting it, they would directly help promote the labour movements struggle that was underway.
As football attracted more and more attention in the city on the Vrbas river, Banja Luka got the right to organise its own sub-association gathering the clubs of the entire Krajina region, a new, bigger and modern stadium was built.
The opening ceremony took place on September 5, 1937, on the ground of the present-day Banja Luka City Stadium.
The club's first success in this early period came in 1928 when RSK Borac won a tournament played in Sarajevo.
In 1961, Borac was promoted to the Yugoslav First League for the first time but was instantly dropped back down at the end of the season.
Borac Banja Luka was the only team who beat R.S.C Anderlecht in one match (at home by 1–0) during the cup season.

At the ceremony, the president of Yugoslav Football Association Antun Čilić gave the golden plaques to Borac players and the head coach.
The next day, tens of thousands of Borac supporters gathered at Krajina square in Banja Luka and gave their team a hero's welcome.
After the elimination of U.S. Foggia in front of 30,000 spectators, Borac met in the final BVSC Budapest at Pino Zaccheria Stadium.
Borac played a total of twelve games in UEFA competitions and has never lost a European match at its home ground.
During the 2010–11 UEFA Europa League season, they played in the second round against FC Lausanne-Sport but were knocked out in front of sold-out Banja Luka City Stadium with 1–2 on aggregate for the Swiss club.
In the following 2011–12 UEFA Champions League season, Borac began its qualifying with a match against Maccabi Haifa, which they lost by 5–1.
[13] In the second leg, Borac showed great performance and won 3–2 by two goals from Krunić and one from Vidaković, however, they were eliminated.
This made them only the second club from Bosnia and Herzegovina to compete in the group or league phase of a European competition.
[citation needed] As one of the most successful football clubs in the country, Borac always had a considerable number of supporters.
