Pha Khao (Thai: ผาขาว; IPA: [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.

[2] The district is divided into five sub-districts (tambons), which are further subdivided into 64 villages (mubans).
