Wubu County (simplified Chinese: 吴堡县; traditional Chinese: 吳堡縣; pinyin: Wúbǔ Xiàn) is located in the southeastern corner of Yulin City, in the north of Shaanxi Province, China, and on the western bank of the Yellow River.

The typical landscape within the county is loess plateau and drought often hovers in the area, creating serious soil erosion.

With an area of 418.5 square kilometres (161.6 sq mi), it is the smallest county in northern Shaanxi.

The area was used by Helian Bobo to detain people loyal to Liu Yu and his Southern dynasty.

During the Northern Han dynasty, a hilltop stone city was built in Wubu.
