Gongsan-dong is an administrative dong (neighborhood) in Dong-gu, in northeastern Daegu, South Korea.
Slightly more than half of the people live in the dong's 38 apartment blocks.
Gongsan Dam, which supplies drinking water for much of northern Daegu, is also located within the boundaries of Gongsan-dong.
Land use in much of the dong is restricted due to regulations protecting the water supply and natural environment.
Because of the relatively low population density, Gongsan-dong encompasses a total of 14 legal dong.
