Na Charoen () is a tambon (subdistrict) of Det Udom District, in Ubon Ratchathani Province, Thailand. In 2021, it had a population of 7,560 people. Neighbouring subdistricts are (clockwise from the south) Som Sa-at, Na Krasaeng, Sa Saming, Pa Mong, Mueang Det, and Tha Pho Si.
Initially, the area was administered by three subdistricts including Na Suang, Som Sa-ad, and Thung Thoeng, but later became a subdistrict in its own right in 1966. Before 1997, the tambon was governed by the Subdistrict Council of Na Charoen (à ¸ªà ¸ à ¸²à ¸Âà ¸³à ¸Âà ¸¥à ¸Âà ¸²à ¹Âà ¸Âà ¸£à ¸´à ¸Â), which was later upgraded to the Subdistrict Administrative Organization of Na Charoen on February 23 that year.
In 1983, the western region of the tambon was splintered off to establish a new administrative division, the Na Krasaeng subdistrict.
The tambon is located in the northwestern region of the Det Udom district, on a plateau with a tropical savanna climate.
The tambon is divided into 10 administrative villages (mubans; à ¸«à ¸¡à ¸¹à ¹Âà ¸Âà ¹Âà ¸²à ¸Â), one of which, Na Charoen village, was further divided into two community groups (Mu; à ¸«à ¸¡à ¸¹à ¹Â). The entire area is governed by the Subdistrict Administrative Organization of Na Charoen (à ¸Âà ¸Âà ¸Âà ¹Âà ¸Âà ¸²à ¸£à ¸Âà ¸£à ¸´à ¸«à ¸²à ¸£à ¸ªà ¹Âà ¸§à ¸Âà ¸Âà ¸³à ¸Âà ¸¥à ¸Âà ¸²à ¹Âà ¸Âà ¸£à ¸´à ¸Â; Na Charoen SAO).
The following is a list of the subdistrict's mubans, which roughly correspond to the villages, as of the 2021 census.
