Tak Fa (Thai: ตากฟ้า, pronounced [tàːk fáː]) is a district (amphoe) in southeastern part of Nakhon Sawan province.

[1][2] The word "Tak Fa" means "sun drying" or "sunbath" in Thai, because the terrain here is a ground and jungle.

[3] Historically, Tak Fa was a hometown of Luang Si Yot, a nobleman during the Ayutthaya period.

Siamese chronicles name him as Luang Si Yot of Ban Lan Tak Fa.

The district is divided into seven sub-districts (tambons), which are further subdivided into 77 villages (mubans).
