First League of the Republika Srpska (Serbian: Прва лига Републике Српске / Prva liga Republike Srpske) is a second level football competition in Bosnia and Herzegovina. Since there were three different football championships in country, organized on ethnic principles, the "First League of the Republika Srpska" was the top flight in Republika Srpska before 2002. However, the champions of this League were not recognized by UEFA. In 2002, the top clubs from Republika Srpska joined Premier League of Bosnia and Herzegovina and the First League was kept as one of two second level divisions. It is still run by the Football Association of Republika Srpska, and has ended its boycott of Bosnian football on a federal level.
The league consists of 14 teams. Each team plays a total of 26 games during the course of a regular season, times each team (once at home and once away). The League champion is promoted to the Premier League at the end of the season, and the bottom clubs are relegated to lower leagues. The number of relegated teams depends on how many clubs are entering the league. That will be the winners of 3 third level leagues, and clubs relegated from Premier League. So, sometimes two clubs will be relegated, and sometimes three or four.
