Tongnyà Âng Prefectures () were administrative divisions of the Mongol-led Yuan dynasty of China located in the northwest Korean Peninsula between 1269 and 1290.
In October 1269, Ch'oe T'an (), Han Sin (), Yi Yà Ânnyà Âng (), Kye Munbi () and Hyà Ân Hyoch'à Âl () rose in rebellion in order to exclude Im Yà Ân (), Military Leader of Goryeo, and surrendered to Yuan dynasty with 60 prefectures and cities in northwest part of Goryeo. In following year, Yuan dynasty established Tonggyà Âng prefecture at former west prefecture. Jabi Pass () as a border belonged to Liaoyang ministry nominated Ch'oe T'an as a commander.
In 1276, Tonggyà Âng prefecture got promoted to Tonggyà Âng circuit. This promotion there was no description in the Koryà Âsa. Also in the clause of August 1276 and February 1290, the description of Tonggyà Âng prefecture can be seen. It is inferred that "Tonggyà Âng circuit" was renamed as "Tonggyà Âng prefecture" shortly.
After this, the political relationship between Yuan dynasty and Goryeo was strengthen. In July 1290, Tonggyà Âng prefecture was abolished and jurisdiction was transferred to Goryeo, ending the prefecture's 20 years of history.
In Koryà Âsa, there were some records (New year's clause in 1364, November's clause in 1369 and new year's clause in 1370) tells that Tonggyà Âng prefecture was established in Yuan dynasty again. However, there were no descriptions about Tonggyà Âng prefecture in China's records after 1290. In the end of Yuan dynasty, it suddenly appeared in Koryà Âsa. There are two hypotheses about this. One is that in 1290, Tonggyà Âng prefecture was not abolished but transferred to Liaoyang area. And the other was that Tonggyà Âng prefecture was abolished in 1290, but reestablished in Yuan dynasty in the period of confusion.
