The district was established at Ban Khao Noi,
Tambon Tha Tako, in 1900. At first there was confusion whether the name was Khao Noi or Don Kha. It got its official name Tha Tako in 1917. 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. At that pier several big Tako trees (
Diospyros sp.) grew, so that pier was called Tha Tako. ==Geography==
