Bueng Bun (Thai: บึงบูรพ์, pronounced [bɯ̄ŋ būːn]) is a district (amphoe) of Sisaket province, northeastern Thailand.

The minor district (king amphoe) was created on 18 July 1977, when the four tambons, Po, Dot, Siao, and Nong Ma were split off from Uthumphon Phisai district.

[3] Neighboring districts are (from the north clockwise): Rasi Salai, Uthumphon Phisai, and Pho Si Suwan of Sisaket Province, and Rattanaburi of Surin province.

The district is divided into two sub-districts (tambons), which are further subdivided into 25 villages (mubans).
