The Capital Cities and Tombs of the Ancient Koguryo Kingdom is a UNESCO World Heritage Site which includes a number of archaeological sites currently in Ji'an, Jilin Province and Huanren, Liaoning Province in Northeast China. (
Goguryeo (Koguryo), (37 BCE – 668 CE) was an ancient kingdom located in what is now Northeast China and the northern Korean Peninsula.

The archaeological sites were collectively designated a cultural World Heritage Site in 2004, qualifying as such under the first five of the six criteria for cultural heritage sites.
The designation includes the archaeological remains of three fortress-cities: Wunü Mountain City, Guonei and Wandu, and forty identified tombs of Goguryeo imperial and noble families.

In 2010, the Chinese government established the Ji'an Gaogouli National Archaeological Park (Chinese: 集安高句丽考古遗址公园), which includes all of the Koguryo (Gaogouli) World Heritage Sites in Ji'an, Jilin, but not the ones in Liaoning (such as Wunü Mountain City).

North Korea initially attempted to register the world heritage of the sites from around 2000.
Although it was scheduled to be registered in 2003, China opposed the sole registration of North Korea and applied for registration of the Goguryeo ruins scattered in Jilin Province.
For this reason, the remains of North Korea and the People's Republic of China were registered in the form of simultaneous registration in 2004.
It is recognized that there is an existence of a question on the history of Goguryeo between North Korea and China.
