Cheolli Jangseong (lit. "Thousand Li Wall") in Korean history usually refers to the 11th century northern defense structure built during the Goryeo dynasty in present-day North Korea, though it also refers to a 7th century network of military garrisons in present-day northeastern China, built by Goguryeo, one of the Three Kingdoms of Korea.

After Goguryeo's victory in the Goguryeo–Sui Wars, in 631 Goguryeo began the fortification of numerous military garrisons after the Tang Dynasty, the successor to the Sui in China, began incursions from the northwest.[1] Its construction was supervised by Yeon Gaesomun during the reign of King Yeongnyu. The preparation and coordination was completed in 647, after which Yeon Gaesomun took control of the Goguryeo court in a coup.
The network of fortresses ran for approximately 1000 li in what is now called Manchuria, from Buyeoseong (부여성, 扶餘城) (present-day 農安) to the Bohai Bay.

Cheolli Janseong also refers to the stone wall built from 1033 to 1044, during the Goryeo dynasty, in the northern Korean peninsula.

It connected the fortresses built during the reign of Emperor Hyeonjong, passing through these cities :
King Deokjong ordered Yuso to build the defenses in response to incursions by the Khitan of the northwest and the Jurchen of the northeast. It was completed during the reign of Emperor Jeongjong.
It ran from the mouth of the Yalu River to around Hamheung of present-day North Korea. Remnants are still extant, including in Ŭiju and Chŏngp'yŏng.
