Pha Khao (Thai: ผาขาว; in Thai pronounced as /pʰǎː kʰǎːw/) is a district (amphoe) of Loei Province, northeastern Thailand.
Neighboring districts are (from the south clockwise): Phu Kradueng, Nong Hin, Wang Saphung, and Erawan of Loei Province; and Si Bun Rueang of Nong Bua Lamphu Province.
The minor district (king amphoe) was established on 1 January 1988, when the four tambons, Pha Khao, Tha Chang Khlong, Non Po Daeng, and Non Pa Sang, were split off from Phu Kradueng.[1] It was upgraded to a full district on 3 November 1993.[2]
The district is divided into five sub-districts (tambons), which are further subdivided into 64 villages (mubans). There are no municipal (thesaban) areas. There are five tambon administrative organizations (TAO).
