Central Sumba Regency (Indonesian: Kabupaten Sumba Tengah) is a regency in East Nusa Tenggara of Indonesia.

The Central Sumba Regency (following the re-organisation of 22 May 2007 which created it out of parts of both West Sumba Regency and East Sumba Regency) was composed of five districts (kecamatan), but a sixth district (Umbu Ratu Nggay Tengah) has since been created by taking 7 villages from Umbu Ratu Nggay District and 3 villages from Umbu Ratu Nggay Barat District.

[1] The table also includes the locations of the district administrative centres, the number of administrative villages in each district (all classed as rural desa), and its postal code.

Note: (a) The populations at the 2010 and 2020 Censuses of the villages now forming the new Central Umbu Ratu Nggay District are included with the figures for the two districts from which they were cut out.
