Singapore Premier League

The Singapore Premier League, commonly abbreviated as the SPL, officially known as the AIA Singapore Premier League for sponsorship reasons, is a men's professional football league sanctioned by the Football Association of Singapore (FAS), which represents the sport's highest level in the Singapore football league system.

The competition was founded as the S. League on 14 April 1996, after the FAS announced its intention to promote and expand the growing local football community by having a top-level domestic league. As of 2025, the league comprises eight clubs, consisting of four rounds in which each team plays every other team once. Seasons run from late August to May, with teams playing 28 matches each, totalling 112 matches in the season.

Successful SPL clubs qualify for Asian continental club competitions, including the AFC Champions League Two. SPL currently does not practice promotion and relegation. Since the league's inception in 1996, 7 clubs have been crowned champions. Warriors have been the most successful club with 9 titles, followed by Albirex Niigata (S) (6), Tampines Rovers (5), Lion City Sailors (4), Geylang International (2), DPMM (2) and Étoile (1). The current champions are Lion City Sailors, having won their fourth league title in the 2024–25 season.

Singapore had been represented in the Malaysia Cup through the Singapore Lions since 1921. The Lions were one of the most successful teams in the competition, having won it 24 times from 1921 to 1994. Following a dispute over gate receipts between the FAS and FAM after winning the league and cup double in 1994, the Lions withdrew from the Malaysian competitions.

Subsequently, FAS decided to build a professional league system. However, as it was estimated to take about a year to put in place the structure of a professional league, the Singapore Lions were given match practice in what was then the top level of domestic football, the semi-professional FAS Premier League. This team won the last FAS Premier League title, finishing the season unbeaten.

The S.League was founded in 1996. The FAS invited applications for clubs to compete in the newly formed league. Eight successful applications were made. Two clubs from the Premier League – powerhouse Geylang International (renamed Geylang United; 6 consecutive Premier League titles) and Balestier United (renamed Balestier Central) – joined six from the amateur National Football League – Police SA, Singapore Armed Forces (SAFFC), Tampines Rovers, Tiong Bahru United, Wellington (renamed Woodlands Wellington) and Sembawang Rangers (merger of Gibraltar Crescent and Sembawang SC) – for the inaugural edition of the S.League. The season was split into two series. Tiger Beer Series winners Geylang United defeated Pioneer Series winners SAFFC 2–1 in the end-of-season championship playoff to be crowned the 1st S.League champions. The 30,000 crowd at the playoff remains the record attendance in the S.League.

Police FC renamed themselves as Home United for the 1997 season to reflect their representation of not only the Singapore Police Force but also other HomeTeam Departments of the Singapore Ministry of Home Affairs such as the SCDF and the ICA. NFL side Jurong Town, who renamed themselves Jurong FC, joined the competition taking the number of participating clubs to 9. The league switched from its previous format to a round-robin competition. Singapore Armed Forces won their first title.

Gombak United and Marine Castle United joined the S.League in 1998, further taking the number of clubs to 11. Tiong Bahru United renamed themselves to Tanjong Pagar United at the start of the season. Singapore Armed Forces won their second consecutive title.
