Ban Fang (Thai: บ้านฝาง, pronounced [bâːn fǎːŋ]) is a district (amphoe) of Khon Kaen province, northeastern Thailand.

The minor district (king amphoe) Ban Fang was established on 1 May 1975 by splitting off four tambons: Nong Bua, Pa Wai Nang, Ban Lao, and Non Khong from Mueang Khon Kaen district.

[2][3] Neighboring districts are (from the north clockwise): Ubolratana, Mueang Khon Kaen, Phra Yuen, Mancha Khiri, and Nong Ruea.

The district is divided into seven sub-districts (tambons), which are further subdivided into 74 villages (mubans).

The township (thesaban tambon) Ban Fang covers parts of tambon Ban Fang.
