Unsan County is a kun, or county, in eastern North P'yŏngan province, North Korea. Within the province, it borders Hyangsan in the east, Kujang and Nyŏngbyŏn in the south, and Tongch'ang and T'aech'ŏn in the west. In addition, it is bordered by Chagang province to the east (Hŭich'ŏn) and north (Songwŏn).
The Kuryong River (구룡강) has formed a steep valley and basin in the centre of the county, into which various tributaries flow including the Uhyŏn River, Choyang River, Ryonghŭng River, and P'ungsanch'ŏn. 73% of the county's area is forested, while only 15.5% is cultivated.
The year-round average temperature is 8.2 °C, with a January average of -10.2 °C and an August average of 23.8 °C. The climate is fairly wet, with an average annual rainfall of 1400 mm.
Of Unsan's cultivated land, most (70%) is dry-field, with numerous cattle farms; local crops include maize, soybeans, sweet potatoes, and vegetables as well as rice. Unsan leads the province in the production of sweet potatoes. Fruit is also raised. Gold and silver are mined, and factories produce textiles and ironware.
