Phu Wiang (Thai: ภูเวียง, pronounced [pʰūː wīaŋ]; Northeastern Thai: ภูเวียง, pronounced [pʰu᷇ː wi᷇aŋ]) is a district (amphoe) in the northwestern part of Khon Kaen province, northeastern Thailand.

A prehistoric Iron Age archaeological site, None Nok Tha (โนนนกทา) is in the district, as is the Phu Wiang National Park.

[1] The district is divided into 11 subdistricts (tambons), which are further subdivided into 114 villages (mubans).

Missing numbers are tambons which now form the districts Wiang Kao and Nong Na Kham.
