The Geum River^[d] is a major river of South Korea that originates in Jangsu-eup, North Jeolla Province. It flows northward through North Jeolla and North Chungcheong Provinces and then changes direction in the vicinity of Greater Daejeon and flows southwest through South Chungcheong Province before emptying into the Yellow Sea near Gunsan city.

The river is 397 kilometres (247 mi) long,^[4] making it the third longest in South Korea. The area of the Geum River Basin is 9,859 square kilometres (3,807 sq mi).^[5] The upper part of the river flows slowly through part of the Noryeongsanmaek Mountains and is marked by extensive stream meandering. On the other hand, river curves on middle and lower parts of the river are more gradual and there is comparatively less stream meandering.

Tributary streams of the Geumgang include the Gap-cheon, Yugu-cheon, Miho-cheon, Unsan-cheon, Seokseong-cheon, and Nonsan-cheon. Several small alluvial plains including the Honam and Nonsan Plain have been formed by the flow of the Geumgang and its tributaries.
