Mueang Surat Thani (Thai: เมืองสุราษฎร์ธานี, pronounced [mɯ̄a̯ŋ sù.râːt tʰāː.nīː]), or colloquially Ban Don District (Thai/Southern Thai: บ้านดอน), is the district of Surat Thani province in southern Thailand.
The district is at the mouth of the Tapi River, where it flows into Bandon Bay of the Gulf of Thailand. Neighboring districts are (from the east clockwise): Kanchanadit, Ban Na San, Ban Na Doem, and Phunphin district.
To the east of the district the Thathong River marks the natural boundary to Kanchanadit, while the boundary to Phunphin is partially marked by the western arm of the Tapi River. Khun Thale is a small lake in the center of the district. The Khao Tha Phet non-hunting area protects 4.65 km2 of a hill south of the city of Surat Thani.
The Khun Thale swamp to the south of the district is the source of two short minor rivers which meander through the city, Khlong Makham Tia and Khlong Tha Kup.
The district was formed when in 1897 Mueang Chaiya and Kanchanadit were merged into a single province named Chaiya, with its administrative center at Ban Don.[1] The district was then named Mueang. In 1915 the province was renamed Surat Thani.[2] In 1917 the district was renamed Ban Don (บ้านดอน).[3] In 1938 the district was renamed Mueang Surat Thani, when all capital districts were named after their corresponding province.[4]
Mueang Surat Thani or Ban Don before World War II period was the location of many businesses lined along the Tapi River, such as sawmills, trade offices, office of East Asiatic Company, including water bus services, which was often called Ruea Naris (เรือนริศ) and the residence of Prince Naris as well.
