Bang Bai Mai (Thai: บางใบไม้, pronounced [bāːŋ bāj máːj]) is a tambon (subdistrict) of Mueang Surat Thani District, Surat Thani Province, southern Thailand.
It is said that Bang Bai Mai in the past, there was a warlord who migrated his family from neighbouring Nakhon Si Thammarat to settle here, because it is a fertile area suitable for cultivation and he himself has had descendants inherited to the present.
Along both sides of the Khlong Bang Bai Mai is mixed deciduous forest.
Bang Bai Mai earned the nickname "Khlong Roi Sai" (คลองร้อยสาย, pronounced [kʰlɔ̄ːŋ rɔ́ːj sǎːj], "a hundred canals") because there are hundreds of small waterways connected to each other.
[2] Bang Bai Mai is governed by two local government bodies: Surat Thani City Municipality and Subdistrict Administrative Organization (SAO) Bang Bai Mai.
