Muara Enim Regency is a regency of South Sumatra Province, Indonesia. The regency seat is the town of Muara Enim. The city of Prabumulih is an administrative body separating the main part of Muara Enim to the south of the city from a smaller part to its north. The regency until late 2012 covered an area of 8,587.94 km² and had a population of 717,717 at the 2010 Census; however, on 14 December 2012 five districts from the Muara Enim Regency were split off to form the new Penukal Abab Lematang Ilir Regency.

The residual regency thus covered 7,486.21 km and within its reduced area had a population of 551,202 at the 2010 Census and 612,900 at the 2020 Census, the latter comprising 312,953 males and 299,947 females; the official estimate as at mid 2023 was 640,224 - comprising 326,519 males and 313,705 females, prior to the intended separation (as stated in late 2022) of another six districts to form the new Rambang Lubai Lematang Regency, which comprised 70 villages (desa) with an area of 2,311.27 km and 172,020 people as at mid 2023.

Mining and agricultural activities are abundant in the regency and it is also a producer of oil. Notable crops include rice and coconuts.

Bumi Serasan Sekundang is located in the heart of South Sumatra Province. The boundaries are:

North	Penukal Abab Lematang Ilir Regency, Banyuasin Regency, Palembang City
South	South Ogan Komering Ulu Regency, Kaur Regency (Bengkulu Province)
West	Musi Rawas Regency, Lahat Regency, Pagar Alam City
East	Ogan Komering Ulu Regency, Rambang Lubai Lematang Regency, Prabumulih City

Muara Enim Regency was divided as at 2000 into twenty-eight districts (kecamatan); however, six of these districts - Rambang Kapak Tengah (Central Rambang Kapak), Prabumulih Timur (East Prabumulih), Prabumulih Selatan (South Prabumulih), Prabumulih Barat (West Prabumulih), Prabumulih Utara (North Prabumulih) and Cambai - were separated from the regency on 21 June 2001 to create the independent city (kota) of Prabumulih, and another five of these districts - Talang Ubi, Penukal, Tanah Abang, Penukal Utara and Abab - were separated out from the regency on 14 December 2012 to form the new Penukal Abab Lematang Ilir Regency. Subsequently, four additional districts (Panang Enim, Lubai Ulu, Belimbing and Belida Darat) were created by the division of existing districts, while the former Rambang Dangku was split into two new districts (Rambang Nuru and Empat Petulai Dangku). Finally in 2022 another new regency - Rambang Lubai Lematang Regency - was announced as intended to be created, to consist of the six districts of Rambang, Lubai, Lubai Ulu, Belimbing, Rambang Niru and Empat Petulai Dangku.

The resulting twenty-two districts (including the six intended to form the new Rambang Lubai Lematang Regency) are listed below with their areas and their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2023. The table also includes the locations of the district administrative centres, together with the number of villages in each district (comprising 245 rural desa and 10 urban kelurahan), and their post code(s). The topography of the regency comprises a southern group of five districts with an altitude of over 100 metres above sea level in the Bukit Barisan mountain chain, a west-central group of five districts, an east-central group of six districts (those intended to be split off), and finally a northern group of six districts of mainly swamp area facing directly with the Musi River basin, which (since the creation of the Penukal Abab Lematang Ilir Regency in 2013) are physically separated from the rest of the Muara Enim Regency by the city of Prabumulih.
