Galhyeon-dong (Korean: 갈현동) is a dong (neighborhood) of Eunpyeong District, Seoul, South Korea.

The northern boundary is Jingwan-dong, while Bulgwang-dong lies to the east.

To the south, it shares borders with Gusan-dong and Daejo-dong, and to the west lies Changneung-dong in Goyang-si, Gyeonggi-do.

The name "Galhyeon" originates from the Chinese character "葛峴", which translates to "Kudzu Pass" or "Galgogae" in Korean.

The Dongguk Yeoji Bigo, a historical record, also refers to this region as "Galgogae".
