同塔省
Tân Phú was established on 12 May 1968, by adding together portions of the old districts of Tân Châu and Châu Phú. In September 1974, Tân Phú and some communes of Đồng Tháp Province were split into two districts in Phú Tân, Tân Phú A and B. In 1976, these two districts were merged to form the current Tân Phú. Phú Tân derives its name from Châu Phú and Tân Châu.
