Seongsu-dong (Korean: 성수동) is a dong, or neighbourhood, of Seongdong-gu in Seoul, South Korea.^[1][2] It is further subdivided into Seongsu-dong 1-ga and Seongsu-dong 2-ga, and is served by Ttukseom Station and Seongsu Station on Seoul Subway Line 2 and by Seoul Forest Station on the Suin-Bundang Line. Its most notable attraction is Seoul Forest, a public park. The neighborhood has become popular in recent years for its array of cafes and restaurants, many of which have been set up in repurposed factories and old residential buildings, earning it the nickname "The Brooklyn of Seoul". There are also various stores built inside repurposed shipping containers.^[3]

Seongsu-dong is a semi-industrial area with small factories adjacent to the Han River and Jungnangcheon Stream, and is expected to develop into a major transportation hub with the opening of Seoul Forest and the opening of the Bundang Line.
