The Ch'ŏngch'ŏn is a river in North Korea having its source in the Rangrim Mountains of Chagang Province and emptying into the Yellow Sea at Sinanju. The river flows past Myohyang-san and through the city of Anju, South P'yŏngan Province. Its total length is 217 km (135 mi), and it drains a basin of 9,553 km (3,688 sq mi).

In 612, at the Battle of Salsu (Salsa - the former name of the Cheongcheong River), the troops of the Korean kingdom of Goguryeo utterly defeated the Chinese army of the Sui Empire that had invaded Korea.

In November–December 1950, in the Battle of the Ch'ongch'on River, detachments of the Korean People's Army and Chinese volunteers won a major victory over the troops of the Americans and their allies during the Korean War.

The river's estuary has been identified by BirdLife International as an 8,000 hectares (20,000 acres) Important Bird Area (IBA) because it supports significant numbers of the populations of various bird species. These include swan geese, bean geese, whooper swans, Oriental storks, black-faced spoonbills, Chinese egrets, great bustards, white-naped cranes, hooded cranes, red-crowned cranes, Far Eastern curlews and spotted greenshanks. The site includes the 800 hectares (2,000 acres) Mundok Nature Reserve.

North Korea is building 10 new hydroelectric dams on the Chongchon River to spur rapid development.
