Uiseong County (Uiseong-gun) is a county in Gyeongsangbuk-do Province, South Korea. Located near the center of the province, it is bounded by Andong on the north, Cheongsong on the east, Gunwi County on the south, and Sangju and Yecheon on the west. As in most parts of Korea, most of the land is vacant and forested; only about 19% of the county's area is farmland.
