Kut Khaopun (Thai: กุดข้าวปุ้น, pronounced [kùt kʰâːw.pûn]; Northeastern Thai: กุดข้าวปุ้น, pronounced [kǔt kʰàːw.pûn]) is a district (amphoe) in the northern part of Ubon Ratchathani province, northeastern Thailand.

The minor district (king amphoe) Kut Khaopun was created on 12 July 1971, when the four tambons Khaopun, Ka Bin, Kaeng Kheng, and Non Sawang were split off from Trakan Phuet Phon district.

[2] Neighboring districts are (from the northeast clockwise) Khemarat, Pho Sai, Trakan Phuet Phon of Ubon Ratchathani Province and Pathum Ratchawongsa of Amnat Charoen province.

The district is divided into five sub-districts (tambons), which are further subdivided into 73 villages (mubans).
