Dalseong County (Dalseong-gun) is a gun occupying much of south and western Daegu, South Korea. A largely rural district lying along the Nakdong River, it makes up nearly half of Daegu's total area. It is divided in half by a narrow piece of Dalseo-gu that reaches west to the river.
Like the other local government units in South Korea, Dalseong-gun enjoys a moderate degree of local autonomy. The county magistrate and council are elected by the local citizens, although their authority is sharply curtailed. The seat of government is located in Nongong-eup. The current magistrate is Lee Jong-jin.
Dalseong-gun enters historical records in 757, as Daegu-hyeon, a subsidiary of Suchang-gun (modern-day Suseong-gu). Dalseong-gun became part of Daegu Metropolitan City in 1995, as part of a general reform of local governments.
The name Dalseong means "Dal Castle," and comes from the earlier name of Daegu, Dalgubeol.
Dalseong-gun is divided into three eup and six myeon. These are in turn divided into 279 ri and 1470 ban.
