Khao Wong (Thai: เขาวง, in Thai pronounced as /kʰǎw wōŋ/) is a district (amphoe) in the eastern part of Kalasin province, northeastern Thailand.
Neighboring districts are (from the south clockwise) Kuchinarai and Na Khu of Kalasin Province, Dong Luang and Khamcha-i of Mukdahan province.
The minor district (king amphoe) was created on 1 June 1969, when the five tambons Khum Kao, Song Plueai, Na Khu, Phu Laen Chang, and Nong Phue were split off from Kuchinarai district.[1] It was upgraded to a full district on 1 April 1974.[2]
The district is divided into six subdistricts (tambons), which are further subdivided into 59 villages (mubans). Kut Sim is a township (thesaban tambon) which covers parts of tambons Khum Kao, Kut Sim Khum Mai, and tambon Kut Pla Khao. There are a further five tambon administrative organizations (TAO).
