Manggarai Regency is a regency in East Nusa Tenggara province of Indonesia, situated on the island of Flores. Established in 1958 the regency was reduced in size and population by the separation of the more western districts to form West Manggarai Regency in 2003 and of the more eastern districts to form East Manggarai Regency in 2007. The area of the residual Manggarai Regency is 1,343.83 km2 and its population was 292,037 at the 2010 census[2] and 312,855 at the 2020 census;[3] the official estimate as at mid 2023 was 328,758 (comprising 164,420 males and 164,338 females).[4] The capital of the regency is the town of Ruteng.
The Liang Bua archeological site is in Manggarai regency, about 10 km to the north of Ruteng.
Manggarai Regency was one of the original regencies of East Nusa Tenggara Province, but was reduced in area and population on 25 February 2003 when some of its western districts were split off to form the West Manggarai Regency (Kabupaten Manggarai Barat), and then reduced again on 17 July 2007 when some eastern districts were split off to form the East Manggarai Regency (Kabupaten Manggarai Timur). The area of the remaining Manggarai Regency as at 2010 was divided into nine districts (kecamatan), but since 2010 three additional districts – Cibal Barat, Reok Barat and subsequently Satar Mese Utara – have been created by splitting of existing districts.
The districts are tabulated below with their areas and their populations at the 2010 census[5] and the 2020 census,[6] together with the official estimates as at mid 2023.[7] The table also includes the locations of the district administrative centres, the number of administrative villages in each district (totaling 145 rural desa and 26 urban kelurahan), and its postal codes.
