The minor district (king amphoe) Kut Khaopun was created on 12 July 1971, when the four tambons Khaopun, Ka Bin, Kaeng Kheng, and Non Sawang were split off from Trakan Phuet Phon district.[1] It was upgraded to a full district on 25 March 1979.[2]
The district is divided into five sub-districts (tambons), which are further subdivided into 73 villages (mubans). Kut Khaopun is a township (thesaban tambon) which covers parts of tambon Khaopun. There are a further five tambon administrative organizations (TAO).
