Mok-dong (Korean: 목동) is a ward of Yangcheon District, Seoul, South Korea.

[1][2] Commonly referred to as a "special education district", the upper-middle to upper-class neighborhood is best known for its abundance of private institutions, or Hagwons, as well as quality public schools.

Also situated in Mok-dong are the Hyperion Towers, the tallest of which is 69 stories or 256 metres (840 ft) tall.

In the 1980s, it was one of the cheapest residential areas in Seoul due to the pollution of the Anyangcheon river, risk of heavy flooding, and the noise of unauthorized factories.

[3] From 1983 when the development plans for the regions were decided, the dong was developed as a high-density residential area by the military government ahead of 1986 Asian Games and the 1988 Summer Olympics, not only to meet growing housing demands in Seoul, but also to fill the void on the way from the airport to the stadiums.
