Western Thailand is a region of Thailand bordering Myanmar on the west, Southern Thailand on the south, and central Thailand on the east.


Thailand's long mountainous border with Myanmar continues south from northern Thailand into western Thailand following the Tenasserim Hills. This narrow region stretches from Bangkok's outer reaches to the border with Myanmar and from the Shan Hills in the north to Chumphon Province in the south.

The geography of the western region is characterised by high mountains and steep river valleys. Western Thailand hosts much of Thailand's less-disturbed forest areas. Water and minerals are important natural resources. The region is home to many of the country's major dams, and mining is an important industry. Many village names in western Thailand rely heavily on the physical geography of the region.[2]

Provinces of western Thailand

According to the six geographical regions established by the National Research Council of Thailand, the western region includes the following provinces:

  2. Phetchaburi (เพชรบุรี)
