Thung Wa (Thai: ทุ่งหว้า, pronounced [tʰûŋ wâː]) is a district (amphoe) of Satun province, southern Thailand.

When the production declined in the 1910s, many natives moved to the farmland of La-ngu minor district, while foreign merchants left the area completely.

In 1930 the government adjusted the administrative structure to the changed economic situation, making La-ngu a district and reducing Thung Wa to a minor district (king amphoe) under La-ngu.

[2] Neighboring districts are (from the north clockwise) Palian of Trang province.

[3] The district is divided into five sub-districts (tambon), which are further subdivided into 35 villages (muban).
