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.

No artefacts from the paleolithic or neolithic periods have been found, but human existence during these periods is suspected based on discoveries from the neighboring Chasong County. Human existence during the Bronze Age is attested from the pottery from the Mumun pottery period. Black pottery, stone axes Bronze daggers, and crescent stone knives found in Gongwidong and Pungryongdong (the dongs that existed when it was still part of greater Kanggye county. Modern day. Kanggye City and Sijung County). In the early Iron Age, knife money from the Ancient Chinese state of Yan was found in Nonamdong (Dong which was part of Kanggye county, modern day Ronam-ri, Sijung County.)
