South Korea’s landscape is threaded with rivers that have helped shape its cities, farmland and coastal settlements—flowing from inland ranges out to the Yellow and Korea Seas. Whether you enjoy hiking along riverbanks, studying watershed maps, or just wonder how waterways connect provinces, this list brings the network into focus.
There are 27 Rivers in South Korea, ranging from Anseong to Yeongsan — for each entry you’ll find below Length (km),Basin area (km2),Provinces / Mouth / Meaning — you’ll find below.
How can I use the length and basin columns to compare rivers?
Length (km) shows a river’s linear scale while Basin area (km2) indicates the land area draining into it; together they help you compare flow potential and regional impact. For example, a shorter river with a large basin can still carry substantial water during rains, so look at both columns to judge size and hydrological importance.
Which column tells me where each river fits geographically or culturally?
The Provinces / Mouth / Meaning column locates a river by administrative region and outlet, and often explains local names or historical significance. Use that field to connect rivers to cities, coastal mouths, and cultural context while consulting length and basin data for physical scale.
