The Han River or Hangang is a major river in South Korea and the fourth-longest river on the Korean peninsula after the Amnok (Yalu), Tuman (Tumen), and Nakdong rivers. The river begins as two smaller rivers in the eastern mountains of the Korean peninsula, which then converge near Seoul, the capital of the country.

The River flows through Seoul and then merges with the Rimjin River shortly before it flows into the Yellow Sea. The two major branches of the river, the Namhan River and the Bukhan River come together at Yangpyeong, Gyeonggi province, at which point it is referred to as the Han River.
