Kwannam, or Gwannam (), is a subregion of Kwanbuk, a region of Korea, in the northeast of the peninsula. Kwannam traditionally encompasses South Hamgyà Âng Province and Wà Ânsan and Munch'à Ân Cities and Ch'à Ânnae, Pà Âptong, Kosan, and Anbyà Ân Counties of Kangwà Ân Province in North Korea.
The region occupies most of South Hamgyong Province, so is often referred to as Hamnam (èë¨) as an abbreviation for the region's primary province. The name Kwannam, however, means "south of the ridge", in reference to the Mach'à Ânryà Âng ridge, a part of the greater Hamgyong Mountains, that runs through South Hamgyong.
