Sukabumi (Indonesia

Sukabumi Regency (Indonesian: Kabupaten Sukabumi, pronounced [kabuˌpat̪ɛn sukaˈbumi]; Sundanese: Kabupatén Sukabumi) is a regency (kabupaten) in southwestern Java, as part of West Java province of Indonesia. The regency seat is located in Palabuhanratu, a coastal district facing the Indian Ocean. The regency fully encircles the administratively separated city of Sukabumi. Covering an area of 4,163.82 km2, the regency is geographically the largest regency in Java island. The regency had a population of 2,341,409 at the 2010 census and 2,725,450 at the 2020 census; the official estimate as at mid 2025 was 2,852,107 (comprising 1,444,445 males and 1,407,662 females), with a large proportion of it living in the northeastern part of the regency that encircles Sukabumi City, south of Mount Gede. A plan to create a new regency, the putative North Sukabumi Regency surrounding Sukabumi city, was considered by the Indonesian government in 2013, but has been deferred until the end of the current moratorium on new creations of regencies. Sukabumi is strategically located south of Jabodetabek (the Jakarta Metropolitan Area) and west of the Bandung Metro, two largest metropolitan area in Indonesia. Geologically, the regency is at the western end of the Cimandiri Fault, which splits the northern plateau from the southern hilly areas. Its southern region is less populated and contains a high level of biodiversity and significant geological heritage, acknowledged in 2015 by UNESCO with the declaration of Ciletuh-Palabuhanratu Geopark located in the southwestern coast of the regency.
