List of tallest buildings in Seoul

This list of tallest buildings in Seoul ranks skyscrapers in the South Korean capital city of Seoul by height. As of March 2024, this list contains 126 buildings that are 150 m (492 ft) tall or higher, of which only 82 are recognized by the Council of Tall Buildings and Urban Habitat.

The tallest building in Seoul is currently the 555 m (1,821 ft) Lotte World Tower with 123 floors, and is the sixth-tallest building in the world.

The tallest buildings in the city are concentrated in four locations: the traditional city center at Jongno, the modern business and financial district in Gangnam along Teheran Road between Gangnam Station and the COEX complex, the financial and political centre on the island of Yeouido, and the affluent residential neighbourhood of Dogok-dong.

Seoul is located in a valley surrounded by mountains with one mountain in the center, Namsan. On top of Namsan is Namsan Tower which is considered an iconic image of the city of Seoul and can be seen from almost anywhere in the city. To maintain this line of sight, many developers have had to set height limits on their buildings. The city also has strict laws about building heights for reasons of national security stressed by the Korean Air Force and U.S. Air Force.
