Tha Muang district

Tha Muang (ท่าม่วง, pronounced [tʰâː mûa̯ŋ]) is a district (amphoe) in the southern part of Kanchanaburi province, central Thailand and is located west of Bangkok.

The district was established in 1898. Later people in the district moved southward to nearby Wat Si Loha Rat Bamrung. They changed the district name to Wang Khanai (วังขนาย). In 1939 Phra Woraphak Phibun, then head of the district, renamed the district Tha Muang after the name of the central tambon.

Neighbouring districts are (from the west clockwise) Dan Makham Tia, Mueang Kanchanaburi, Phanom Thuan, Tha Maka of Kanchanaburi Province, Ban Pong, and Chom Bueng of Ratchaburi province.

The important water resource is the Mae Klong River. The Mae Klong Dam on the Mae Klong River is in the district.

The district is divided into thirteen subdistricts (tambons), which are further subdivided into 119 administrative villages (mubans).

As of December 2024 there are: nine municipal (thesaban) areas in the district: these are subdistrict municipalities (thesaban tambons) of which Muang Chum, Wang Khanai and Wang Sala cover the whole subdistrict; Nong Khao, Nong Tak Ya, Tha Lo and Tha Muang cover parts of the same named subdistrict; Nong Ya Dok Khao covers parts of Nong Tak Ya and Sam Rong covers parts of Phang Tru subdistrict. Also parts of Tha Lo subdistrict belongs to Kanchanaburi town municipality.

The non-municipal areas are administered by eight subdistrict administrative organizations - SAO (ongkan borihan suan tambon - o bo toh).
