The name "Daerim" is a combination of characters from neighboring areas, Sindae-dong and Sindorim-dong. Contrary to its name, Daerim-dong was not historically a forested area but rather a grassy field and pastureland along the
Dorimcheon
stream.
During the
Joseon Dynasty
, it was part of Geumcheonhyeon Sangbuk-myeon Wonjimok-ri. Over the years, it went through various administrative changes, belonging to different regions and counties. In 1949, it became part of
Seoul
as Sindorim-dong in
Yeongdeungpo-gu
. In 1955, the administrative district of Daerim-dong was established, governing the legal districts of Sindorim-dong and Sindae-dong.
Subsequent changes in district names and boundaries led to the designation of the remaining area of Sindorim-dong in Yeongdeungpo-gu as the legal district of Daerim-dong, which remains unchanged to this day.
