Administrative districts East Kutai Regency is divided into eighteen districts (kecamatan), tabulated below with their areasBadan Pusat Statistik, Jakarta, 28 February 2025, Kabupaten Kutai Timur Dalam Angka 2025 (Katalog-BPS 1102001.6404) and their 2010 and 2020 census populations, together with the official estimates as at mid 2025.Badan Pusat Statistik, Jakarta, 27 February 2026, Kabupaten Kutai Timur Dalam Angka 2026 (Katalog-BPS 1102001.6404) The table also includes the locations of the district administrative centres, the number of administrative villages in each district (a total of 139 rural desa and 2 urban kelurahan), and its postal codes.
The districts are grouped for convenience into three geographical sectors (non-administrative), reflecting proposals which have been considered for dividing the present regency into three new regencies:
(i) The western sector is entirely inland, and equates to what was proposed as a new North Kutai Regency (), with its proposed capital at Muara Wahau. The district of Muara Kaman (in Kutai Kartanegara Regency) is situated immediately south of this area and is effectively a continuation of it. (ii) The southeastern sector includes all of the districts along the southeast coast of the regency, including the most heavily populated areas around the town of Sangatta and the independent city of Bontang. (iii) Finally, the last five districts listed in the table below form the northeast corner of the regency, comprising the southern slopes of the Sambaliung Mountains (Pegunungan Sambaliung), which here creates a large peninsula (whose northern half is in Berau Regency) projecting eastwards into the Makassar Strait, and drained by the Karengen River, which reaches at sea at the main town of Sangkulirang; here the proposal was to separate off these five districts to create a new Sangkulirang Regency () with its proposed capital at Sangkulirang.
