Changgang County is a kun, or county, in north-central Chagang province, North Korea. Originally part of Kanggye, it was made a separate county in 1949. It borders Hwapyong and Rangrim to the east, Kanggye and Sijung to the west, Songgan to the south, and Chasong to the north.
The terrain of Changgang is rugged and mountainous, with the Kangnam Mountains in the northeast and the Chogyuryong Mountains in the southwest. The highest peak is Kumpasan (금파산, 1918 m) along the northern border.
There are soft-drink, clothing and pharmaceutical factories in the county. Rice is grown along the Chongsong River (종성강); various other agricultural produce are grown in the large areas of land which Kim Il-sung suggested be cleared in a 1974 letter. 75% of the county is for agricultural purposes, most of which are fields. Animals are raised in the county, utilising mountains and fields for grazing. Logging takes place in the county, with production and processing of the wood taking place in the county.
The largest industry in the county is hydroelectricity generation, followed by mining. Zinc, graphite, fluorite and lead is mined. The county has a number of small to medium sized hydropower stations, fed by larger hydropower stations such as the Kanggye Youth Power Plant.
