Huai Krachao (Thai: ห้วยกระเจา, in Thai pronounced as /hûa̯j krā.t͡ɕāw/) is a district (amphoe) in the eastern part of Kanchanaburi province, central Thailand.
Tambons Huai Krachao, Wang Phai, Sa Long Ruea, and Don Salaep were separated from Phanom Thuan district and formed the minor district (king amphoe) Huai Krachao on 30 April 1994.[1] It was upgraded to district status on 11 October 1997.[2]
Neighboring districts are (from the south clockwise) Phanom Thuan, Bo Phloi, Lao Khwan of Kanchanaburi Province and U Thong of Suphanburi province.
The district is divided into four sub-districts (tambons), which are further subdivided into 67 villages (mubans). There are no municipal (thesaban) areas. There are four tambon administrative organizations (TAO).
