Hyesan (Korean pronunciation: [he.san]) is a city in the northern part of Ryanggang province of North Korea.

The city is located in the Paektu Mountains at the border with the People's Republic of China (Jilin province), from which it is separated by the Yalu (Amrok) River.

Residents of the city reputedly wash their clothes in the river because homes have no running water.

At that time, the mine flooded because the pumping device stopped operating due to the lack of electricity across the country.

In 1996, during the North's 'Arduous March', electricity was not provided to the mine, leading to flooding in the mineshafts in January 1997.

Hyesan is connected to other cities in North Korea by road, and by the Paektusan Ch'ŏngnyŏn and Pukbunaeryuk lines of the Korean State Railway.

The countryside near Hyesan has various attractions, including the Kwaegung Pavilion, Naegŏk Hot Spring and Mount Paektu.
