Châu Thành is a district in the west of Tây Ninh province in the Southeast region of Vietnam.
The eastern side of the province borders Hòa Thành district and Tây Ninh City.
The west borders Cambodia, the north abuts Tân Biên and the south adjoins Bến Cầu.
There is a sizable minority of Khmer people living in the area, and they now interact with the ethnic Vietnamese majority more than in the past, when communities were more segregated.
There are many unexploited farming plains in the area, more so than in the rest of the province, due to a lack of irrigation infrastructure.
