The Serbian First League (Прва лига Србије / Prva liga Srbije), referred to as the Mozzart Bet First League (Моцарт Бет Прва лига / Mozzart Bet Prva liga) for sponsorship reasons, is the name for the second tier in professional Serbia's football league.

Format
The league is usually formed by 16 clubs which play all against one another twice, once at home, once away. Due to the COVID-19 pandemic in 2020, the Football Association of Serbia completed a restructure of the league system, and in season 2020/2021 that meant 18 clubs would be competing in the Serbian First League, the number of clubs will go back to the usual 16 following the conclusion of the 2020-2021 season. The top two clubs are directly promoted to the Serbian SuperLiga, Third team going into the playoff, and playing against 14 teams from the Super League, while the bottom are relegated to the Serbian League. The Football Association of Serbia announced that in the 2015–16 Serbian First League 4 clubs will be relegated.

History
The Serbian First League is the successor of the Yugoslav Second League. With the break-up of SFR Yugoslavia in 1992, the clubs from the newly independent states of Bosnia and Herzegovina, Croatia, Macedonia and Slovenia joined to their own newly formed leagues, while Serbia and Montenegro remained united and renamed into FR Yugoslavia with the clubs from both republics kept competing in the league. In 2003, the Federal Republic of Yugoslavia was renamed to Serbia and Montenegro and the football league followed suit. Finally, after Montenegrin independence in 2006, the Montenegrin clubs withdrew and formed their own league.
