Bang Chalong (, ) is a tambon (subdistrict) of Bang Phli District, in Samut Prakan Province, Thailand. In 2017, it had a total population of 41,834 people.
The name "Bang Chalong" is believed to derive from the Khmer word "Chanlong" (à ¸Âà ¸£à ¸£à ¹Âà ¸¥à ¸Â), which literally means "lifting." This refers to the act of lifting yo (à ¸¢à ¸Â), a traditional Thai fishing gear, or boats from the waters of the local canal, Khlong Bang Chalong. The word "Bang" denotes a riverside or waterfront community. Thus, Bang Chalong can be translated as "the place of lifting."
The tambon is subdivided into 11 administrative villages (muban).
The area of the subdistrict is shared by 2 local governments.
