Sinch'ŏn is bordered to the north by Anak, to the west by Samch'ŏn and T'aet'an, to the sough by Pyŏksŏng and Sinwŏn, and to the east by Chaeryŏng. Most of the land in Sinch'ŏn is composed of flat plains, with mountains forming its borders. The highest point is Mt. Ch'ŏnbong, at 627 meters. 
The Koryo dynasty named the area occupied by Sinch'ŏn as Sinju. It received its current name under the Yi dynasty in 1413. In 1909 Sinch'ŏn was annexed to Munhwa, now no longer extant. The county's current form was settled in the 1952 redistricting changes, in which its eastern part was annexed to newly formed Samch'ŏn county.
At the beginning of the Korean War in 1950, the town of Sinch'ŏn was allegedly the site of a massacre of civilians by occupying U.S forces (see Sinchon Massacre). North Korean sources claim the number of civilians killed over the 52-day period at over 35000 people, equivalent to one-fourth the county of Sinchon's population at the time. The North Korean government has operated the Sinchon Museum of American War Atrocities in Sinch'ŏn Town since 1958, displaying relics and remains from the incident.
The county is divided into one town (ŭp) and 31 villages (ri).
