Don Phut (Thai: ดอนพุด, pronounced [dɔ̄ːn pʰút]) is a district (amphoe) in the western part of Saraburi province, Thailand.

Tambon Don Phut, Dong Ta Ngao, Ban Luang and Phai Lio were separated from Ban Mo district to create the minor district (king amphoe) Don Phut on 31 May 1971.

[2] Most of the inhabitants of this district are Phuan who migrated from Chiang Khong, Luang Phrabang and Vientiane in the reign of King Rama II.

The district is divided into four sub-districts (tambons), which are further subdivided into 28 villages (mubans).

Dong Ta Ngau is administered by a Tambon Administrative Organization (TAO), the only one in the district.
