East Flores Regency (Indonesian: Kabupaten Flores Timur) is a regency in East Nusa Tenggara province of Indonesia. Established in 1958, the regency has its seat (capital) in Larantuka on Flores Island. It covers a land area of 1,812.58 km2, and it had a population of 232,605 as of the 2010 census[2] and 276,896 at the 2020 Census;[3] the official estimate as of mid-2023 was 288,310 - comprising 141,738 males and 146,572 females.[4] The regency encompasses the eastern tip of the island of Flores, together with all of the adjacent islands of Adonara and Solor to the east of Flores (and both part of the Solor Archipelago), with some much smaller offshore islands. On 4 October 1999, the island of Lembata (formerly called Lomblen) at the eastern end of the Solor Archipelago was separated from the East Flores Regency to create its own Regency.
The regency is divided into nineteen districts (kecamatan), tabulated below with their areas and their populations at the 2010 Census[5] and the 2020 Census,[6] together with the official estimates as of mid-2023 (rounded to the nearest 100 persons).[7] The table also includes the locations of the district administrative centres, the number of administrative villages in each district (totaling 229 rural desa and 21 urban kelurahan), and its postcode.
