Changhan (Thai: จังหาร, in Thai pronounced as /tɕāŋ.hǎːn/; จังหาร, in Lao pronounced as /tɕāŋ.hǎːn/) is a district (amphoe) in the northwestern part of Roi Et province, northeastern Thailand.
Neighboring districts are (from the east clockwise): Chiang Khwan and Mueang Roi Et of Roi Et Province; Mueang Maha Sarakham of Maha Sarakham province; Khong Chai and Kamalasai of Kalasin province.
The minor district (king amphoe) Changhan was established on 1 April 1989, when five tambon were split off from Mueang Roi Et district.[1] Tambon Yang Nai was split from tambon Pa Fa in July 1989, and Phakwaen from Muang Lat in July 1990. On 8 September 1995 the minor district was upgraded to a full district.[2]
The district is divided into eight sub-districts (tambons), which are further subdivided into 110 villages (mubans). There are no municipal (thesaban) areas; there are eight tambon administrative organizations (TAO).
