Ban Pong is a district (amphoe) of Ratchaburi Province, Thailand in the northeast of the province. Neighbouring districts are (from the north clockwise) Tha Muang and Tha Maka of Kanchanaburi Province, Kamphaeng Saen and Mueang Nakhon Pathom of Nakhon Pathom Province, and Photharam of Ratchaburi Province. Ban Pong District is hilly in the western part of the district, while the eastern part is a flood plain with the Mae Klong River running through the city centre, connecting the city to the Gulf of Thailand.
The Mon people settled in the Ban Pong area about four centuries ago. The Mon communities have maintained some of their traditions and have built their own Buddhist temples. Later the town attracted numerous Chinese immigrants. Also many Lao Wiang communities settled in the Nong Kop subdistrict of rural Ban Pong. During the Japanese-directed construction of the Burma Railway in World War II Ban Pong was the site of one of the Japanese POW camps, Nong Pladuk, where numerous British and Allied troops were held. Two great fires occurred in Ban Pong, razing the town centre: one in 1936 and the other in 1954. The town was rebuilt in the square-grid design then fashionable, with a fountain to the south and a clock tower to the north.
Ban Pong is a railway hub, where the western railway leading to Kanchanaburi (and further to Nam Tok) splits from the southern railway leading to Singapore. Another branch connects with the town Suphanburi to the north.
Economic development has been rapid in recent years dominated by the manufacture of auto parts, production of buses and coaches, petrochemical and food industries. Most traditional industies still exist including sugar refining, canning and paper making.
The district is divided into 15 sub-districts (tambons), which are further subdivided into 182 villages (mubans). Ban Pong itself is a town (thesaban mueang) which encompasses tambon Ban Pong.
