Geumseong is a dong (neighborhood) in Geumjeong District, Busan, South Korea.

A lightly populated district, it is situated entirely within the mountain range of Geumjeongsan.

Geumseong-dong is a rural district connected by public transit to the rest of Busan by bus service only.

Despite covering a comparatively large area, Geumseong-dong is not subdivided into additional "administrative dong" due to its low population.

There are two points of access to the dong where the main road, Sanseong-ro, connects to Hwamyeong-dong in the west, and Jangjeon-dong in the east.
