Liga Nusantara (English: Archipelago League), officially known as PNM Liga Nusantara for sponsorship reasons, is the third-tier of the football competition system in Indonesia, organized by Football Association of Indonesia (PSSI). The competition started in 2014 after PSSI merged the previous competitions, Liga Indonesia Second Division and Liga Indonesia Third Division. The competition was previously organized in two phases, with the provincial phase operated by PSSI Provincial Associations, where each province held its own regional competition, followed by the national phase operated by PSSI, where the top teams from each province competed at the national level. Starting from the 2024–25 season, the competition is organized on a national level with teams divided into several groups based on geographical factors and is now operated by Liga Indonesia Baru.
