Non Thai (Thai: โนนไทย, in Thai pronounced as /nōːn tʰāj/) is a district (amphoe) of Nakhon Ratchasima province, northeastern Thailand.
Originally, the area was Khwaeng San Thia (แขวงสันเทียะ). San Thia is Khmer, meaning 'a place to gather salt'. The name refers to the tradition of salt production in the area.
In 1900, Khwaeng San Thia was changed to a district and renamed Non Lao. The following year it was named San Thia. In 1919, the district name was changed to Non Lao again.[1] Finally in the phase of Thai nationalism under Field Marshal Plaek Phibunsongkhram, the district name was changed to Non Thai in 1939 to remove the reference to the Lao population in the name.[2]
Neighbouring districts are (from the north clockwise): Phra Thong Kham, Kham Sakaesaeng, Non Sung, Mueang Nakhon Ratchasima, Kham Thale So, and Dan Khun Thot.
Non Thai is divided into 10 sub-districts (tambons), which are further subdivided into 133 administrative villages (mubans).
