Muara Gembong is the most northerly district (kecamatan) of Bekasi Regency, in West Java, Indonesia. It covers an area of 160.54 km², and had a population of 35,503 at the 2010 Census and 40,321 at the 2020 Census; the official estimate as at mid 2023 was 43,722, comprising 22,362 males and 21,360 females.^[1] The administrative centre is located at Pantai Mekar, and the district is sub-divided into 6 villages (desa), all sharing a post-code of 17730, as listed below with their areas and their populations as at mid 2023.^[1]

As of the 2020 Indonesian census, the district had a population of 40,321, with an average population growth rate of 1.24% annually since 2010. The gender ratio in mid 2023 was 104.69.^[1]

The district includes the delta of the Citarum River, where significant sedimentation still occurs.^[2] It is located on the Bay of Jakarta.^[3]

Since around 2009, coastal erosion has heavily impacted the low-lying, coastal villages, with several rukun tetangga (neighborhood-level administrative divisions) having been lost to the sea. The local government has been attempting to reduce the impact through the plantation of mangrove trees in vulnerable areas,^[4] which are prone to coastal flooding.^[5]

Since at least the 1970s, the coastal communities has been engaging in milkfish and shrimp farming.^[6]
