Ban Khok (Thai: บ้านโคก, pronounced [bâːn kʰôːk]) is the northeasternmost district (amphoe) of Uttaradit province, northern Thailand.

The minor district (king amphoe) Ban Khok was established on 1 July 1977, when the two tambon Ban Khok and Muang Chet Ton were split off from Fak Tha district.

The disputed area of 19 km2, covering three villages and about 1000 inhabitants, was finally given to Laos.

The district is in the Luang Prabang Range mountain area of the Thai highlands.

[5] The district is divided into four sub-districts (tambon), which are further subdivided into 28 villages (muban).
