Tha Song Yang (Thai: ท่าสองยาง, pronounced [tʰâː sɔ̌ːŋ jāːŋ]) is the northwesternmost district (amphoe) of Tak province, western Thailand.
In 1948 the government moved Tha Song Yang to be a subordinate of Mae Sot District, Tak Province.
[1] The following year the district office was moved to Tambon Mae Tan.
Mae Moei National Park is in Tha Song Yang.
The district is divided into six sub-districts (tambons), which are further subdivided into 56 villages (mubans).
