Yeonhui-dong (Korean: 연희동) is a dong (neighbourhood) at the center of Seodaemun District, Seoul, South Korea.

A strategic position during the Korean War (Hill 104), the area is bordered by Hongjecheon to the West (a stream overlooked by an important expressway), Ansan to the East (the mountain where Yonsei University is located), and Yeonnam-dong (Mapo District) to the South.

Under the Japanese occupation, it was sent to Gyeonggi Province, and returned to Gyeongseong-bu (Seoul) as Yeonhui-jeong (延禧町).

Many expat families live in this essentially low rise and residential area.

If the Chinese community is less visible than a couple of years ago, some restaurants and shops subsist, particularly along Yeonhuimat-gil.
