Pho Tak (Thai: โพธิ์ตาก, pronounced [pʰōː tàːk]) is a district (amphoe) of Nong Khai province, northeastern Thailand.

Neighboring districts are (from the west clockwise): Sangkhom, Si Chiang Mai, and Tha Bo of Nong Khai Province, and Ban Phue of Udon Thani province.

The minor district (king amphoe) was created on 1 July 1997 by splitting off the three tambons, Pho Tak, Phon Thong, and Dan Si Suk, from Si Chiang Mai district.

[3] The district is divided into three sub-districts (tambons), which are further subdivided into 27 villages (mubans).
