The Yalu River (called the Amrok in Korea) is a river on the border between North Korea and China. Together with the Tumen River to its east, and a small portion of Paektu Mountain, the Yalu forms the border between North Korea and China and is notable as a site involved in military conflicts in the First Sino-Japanese War, the Russo-Japanese War, and the Korean War.

Evan Hunziker swam from China across the Yalu River in 1996. He spent three months in custody there before being released and returned to the United States thanks to the negotiation efforts of then-New Mexico congressman Bill Richardson.
