Bueng Kum was separated from Bang Kapi on 4 September 1989. It consisted of three sub-districts: Khlong Kum, Khan Na Yao, and Saphan Sung. On 14 October 1997, Khan Na Yao and Saphan Sung were elevated to districts, leaving Bueng Kum with a sole sub-district, Khlong Kum.
Bueng Kum was named so because of a lake ("bueng" means 'lake') used as water reservoir for flood prevention. There are also plants called "kum" (Crataeva sp.) around the lake. The lake is part of Seri Thai Park.
Administration
The district is divided into three sub-districts (khwaeng).
