Tha Faek (Thai: ท่าแฝก, pronounced [tʰâː fɛ̀ːk]) is a tambon (sub-district) of Nam Pat District, in Uttaradit Province, Thailand.

[1] The sub-district originally was part of Tha Pla District.

With the creation of the Sirikit Dam in 1972, the sub-district has become separated from the central part of Tha Pla District.

Effective 14 February 2015, the sub-district was reassigned to Nam Pat District to make the authorities easier to reach for the local residents.
