Liga 4 (English: "League Four") is the fourth-tier of the football competition system in Indonesia, and the only amateur league football competition in Indonesia. The competition is organized by Football Association of Indonesia (PSSI) and the first season starts in 2024.
History.
From 2015 to 2023, there was no fourth-tier competition in the Indonesian football league system following the merger of Liga Nusantara with the First Division, which resulted in the formation of Liga 3 as the lowest tier of the national league structure.
In 2024, PSSI restructured the league system and reintroduced the fourth-tier competition under the name Liga 4, following the elevation of Liga 3 to a semi-professional status operated by Liga Indonesia Baru.
