Tô Hiến Thành (Hán tự: 蘇憲城) (died 1179) was an official in the royal court of Lý Anh Tông and Lý Cao Tông, the sixth and seventh emperors of the Lý Dynasty. Being a capable official of Lý Anh Tông who helped the emperor in civil and military matters, Tô Hiến Thành was chosen by Lý Anh Tông for the regentship of his son Lý Long Trát. He was granted the title Prince and thus became the only possessor of the title who did not come from the Lý royal family. The achievements and loyalty of Tô Hiến Thành to the infant emperor Lý Cao Tông made him a highly praised figure in the history of Vietnam. Today, Tô Hiến Thành is considered one of the most prominent mandarins in the dynastic time of Vietnam.
