The Brunei Super League (abbr: BSL; Malay: Liga Super Brunei ^[1] – LSB) is a professional league for men's association football in the sultanate of Brunei Darussalam. It is at the top tier of the Bruneian football league system, and it is managed by the Football Association of Brunei Darussalam (FABD). The football clubs participating in this top tier league need to pass a set of requirements and verification process, particularly related to professionalism and infrastructure feasibility.^{[clarification needed]}

The BSL championship winner will receive B$15,000 as prize money, in addition to a qualifying berth for the AFC Cup as Brunei's representative, provided that the winning club conforms to Asian Football Confederation (AFC) Club Licence criteria. The BSL runners-up will receive B$10,000.^{[citation needed]}

There has been a football competition in Brunei Darussalam since 1985, which was organised by the then Brunei Football Association (BAFA). In 2002, BAFA introduced a league competition known then as the Proton B-League.^[2]

In 2008, the Brunei government de-registered BAFA from its Register of Societies for failing to provide reports of its annual general meeting and other required documentation.^[3][4] Subsequently, a new football federation, the Football Federation of Brunei Darussalam (FFBD) was established.^[5] This irked FIFA, international football's governing body, and prompted FIFA to suspend Brunei's membership in September 2009 due to government interference.^[6] Subsequently, in May 2011, FIFA reinstated Brunei, recognising another football association, the National Football Association of Brunei Darussalam (NFABD) as its representative for Brunei Darussalam.^[7] This resulted in the abandonment of the 2011 Brunei Premier League (BPL) which was organised by the FFBD.^[8]

The NFABD reorganised the Brunei football league system, establishing a 'super league' as the competition's top tier (akin to the British Premier League, but mirroring the current league naming system of the Malaysia Super League), becoming the Brunei Super League (BSL; Liga Super Brunei, LSB). This was established after playing a preliminary competition, which decided the teams that was to form the new league. This became the 2011–12 Brunei National Football League, where thirty-two teams in four groups qualify for ten club places in the Brunei Super League.^[9]

The founding team club members of the Brunei Super League were: Indera FC, Jerudong FC, Kilanas FC, LLRC FT, Majra United FC, MS ABDB FT, MS PDB, Najip FC, QAF FC, and Wijaya FC.^[10]

In the 2020 season, the league was expanded to sixteen club teams in accordance to FIFA, Asian Football Confederation (AFC), and ASEAN Football Federation (AFF) aspirations.^[11]

Players aged 35 years and over must produce a medical fitness certification to be registered for the league.^[12] Each match-day squad must contain a minimum of four under-21 players, with at least two u-21 players in the starting eleven.^[12]

At the end of each BSL season, the team champion is crowned. Any tiebreakers in the standings are subordinately classified in descending order: accrued points, goal difference, goals scored, head-to-head record between tied teams, goal difference between tied teams, goals scored between tied teams, and drawing of lots.^{[citation needed]}

The 2023 Brunei Super League season, officially known as Liga Super Brunei 2023, consists of sixteen football club teams in the competition.^[1][13] AKSE Bersatu and Lun Bawang^[13] are the two promoted sides from the lower district leagues.^[14]
