Since 1994, Liga Indonesia is the league competition featuring association football clubs, as a result of two existing top-flight football leagues merger: Perserikatan (amateur) and Galatama (semi professional).

Until 2017, it  was known as "Indonesian Super League." The second-tier is Liga 2, formerly "Premier Division". Liga 1 and 2 are professional leagues and governed by PT. Liga Indonesia Baru. The only amateur league is Liga 3. Liga 3 consists of an unlimited number of amateur teams. Every province, in total 34 provinces in Indonesia, holds its own provincial league and the number of teams per province may vary.

From 1914 to 1930, Indonesia featured an amateur national football league organized  by the Nederlandsch Indische Voetbal Bond (NIVB), called the Dutch East Indies city championship (DEI Championship). Beginning in 1931, the Perserikatan was founded as a separate amateur national football league system consisting of several levels of competition. It was the first Indonesian football league competition organized by PSSI. From 1932 to 1950, the DEI Championship competition ran in conjunction with the Perserikatan as a competition for the Dutch and other European players, while the Tiong Hoa Championship was held for players of Chinese descent. In 1979/80, a semi-professional league was founded, namely Galatama ("The Premier League"), which consisted of  only one level of competition (except 1983 and 1990 in which it involved 2 divisions). Therefore, since 1979, both Galatama and Perserikatan were existed and had their own league systems. In 1994, PSSI merged both competitions into a new competition system, namely the "Liga Indonesia". All clubs from both top level leagues were merged into the Liga Indonesia Premier Division, the new system's top-flight league. Furthermore, since Galatama did not have lower-level leagues, Liga Indonesia's lower leagues took all clubs from the same level in Perserikatan. In 2008, PSSI created a new level, the Indonesia Super  League (ISL), as the system's new top-flight league. Hence, the Premier Division was then relegated to the second and so on. This new league was created to introduce full professionalism in Indonesian football. In parallel with this league, U-21 teams from each participating ISL clubs compete in the ISL U-21. In 2011, PSSI replaced the ISL with the Indonesian Premier League (IPL). After the extraordinary congress on 17 March 2013, Premier League and Super League are in PSSI supervision prior to incorporation in 2014 under the name of Indonesia Super League. Before that the two leagues still running , respectively. In 2014, PSSI divided into four level leagues competition include Super League, Premier Division, First Division and Amateur League/Province League called Liga Nusantara. Started in 2015 league planned just divided into three level leagues competition include Super League, Premier Division and Liga Nusantara, after first division merged with Liga Nusantara. In 20 January 2017, PSSI announced to replace three previous league (Super League, Premier Division and Liga Nusantara) with three new leagues, namely the Liga 1, Liga 2 and Liga 3. Competition format. From the 1994–1995 to 2004–2005 season, Liga Indonesia's structure changed almost every year. For  some seasons, there were two divisions within the top flight; for others, there were three. The number of clubs in the top flight wavered from 18–28, and seasons would last from 34–38 games. The top four clubs in each division qualified for a group stage "Final Eight Championship Playoff." Winners of the group faced off for the championship. During the 2004–2005 season, 18 clubs comprised the Indonesian top flight. A season lasted 34 games, in which each club played against each other on a home-and-away basis. The three teams at the bottom of the table are relegated into  Division Satu, the second level of the Indonesian league system, while the three teams of Division Satu that won promotion replace them. The top two finishers in the league qualify for the AFC Champions League. Starting with the 2003–2004 season, the championship was decided a double round-robin league system involving the top clubs of each division. Beginning with the 2005–2006 season, 28 clubs will comprise Liga Indonesia. Clubs compete in two divisions of 14 clubs each. Each club plays against each other on a home-and-away basis. The league's popularity has grown so much that the 2006–2007  season will see another big expansion of the league from 28 to 36 clubs with both divisions comprising 18 clubs each. In 2008, 18 top ranked clubs in the previous Premier Division were 'promoted' to a new highest level of competition, the Indonesia Super League, and the rest stayed in the same division. The PSSI examined those 18 clubs for their readiness to join the ISL, considering many aspects, like the stadium, financial condition and other requirements for full professional football clubs.
