Sinŭiju is bordered by the Amnok River, and by P'ihyŏn and Ryongch'ŏn counties. The city's altitude is 4 feet, or about one meter, above sea level. There are several islands at the mouth of the Amnok River - Wihwa-do, Rim-do, Ryuch'o-do and Tongryuch'o-do.

Developed as a major settlement during the colonial rule at the terminus of a railway bridge across the Amrok River, Sinuiju is located 7 miles south by southwest of Ŭiju, the old city from whose name Sinŭiju (meaning “New Ŭiju”) derives. As an open port, it grew commercially with the logging industry which uses the Amnok River to transport lumber. Additionally, a chemical industry developed after the hydroelectric Sup'ung Dam was built further up the river.
