Tha Tako (Thai: ท่าตะโก, pronounced [tʰâː tā.kōː]) is a district (amphoe) in the eastern part of Nakhon Sawan province, central Thailand.

The district was established at Ban Khao Noi, Tambon Tha Tako, in 1900.

In the past, the people in the district used to visit a substantial river pier (in Thai tha) to bathe and give water to their cattle.

Neighboring districts are (from the north clockwise): Nong Bua, Phaisali, Tak Fa, Phayuha Khiri, Mueang Nakhon Sawan, and Chum Saeng.

The district is divided into 10 sub-districts (tambons), which are further subdivided into 109 villages (mubans).
