South Lampung Regency (Indonesian: Kabupaten Lampung Selatan) is a regency of Lampung, Sumatra, Indonesia, a strip of land surrounding the provincial capital of Bandar Lampung on its northern and eastern sides, and bounded to the west by the new Pesawaran Regency and to the south by the Sunda Strait; as such it is a major transit corridor to/from Java island. It has an area of 2,109.74 km2, and a population of 909,989 at the 2010 census[2] and 1,064,301 at the 2020 census;[3] the official estimate as at mid 2023 was 1,101,376 (comprising 560,209 males and 541,167 females).[4] The regency seat is the town of Kalianda.
South Lampung Regency originally comprised a larger share of the area of Lampung Province, but on 3 January 1997 its far west districts were split off to create a new Tanggamus Regency (then including what became Pringsewu Regency in 2008), and on 14 August 2007 the western districts of the remaining South Lampung Regency were also split off to create a new Pesawaran Regency.
The regency has seen a population influx as migrants escape the crushing population densities and everyday struggles of living in the massive urban paralysis of Greater Jakarta, and along with Bandar Lampung city its character is increasingly reflecting the cosmopolitan makeup of Jakartans rather than the surrounds of a typical provincial capital and hinterland. This has resulted in flaring of ethnic tensions, including rioting.[5]
South Lampung Regency consists of seventeen districts (kecamatan), tabulated below with their areas and their populations at the 2010 census[2] and the 2020 census,[3] together with the official estimates as at mid 2023.[6] The districts are grouped below for descriptive convenience into a "Northern zone" comprising the heavily populated areas suburban to Bandar Lampung city, and a "Southern zone" comprising the areas to the southeast of Bandar Lampung; these zones have no administrative significance. The table also includes the locations of the district administrative centres, the number of administrative villages in each district (a total of 256 rural desa and 4 urban kelurahan, the latter all in Kalianda District), and its post code.
