Julu (Chinese: 巨鹿; pinyin: Jùlù) is a county of Xingtai City, in southern Hebei province, China. Prior to the Sui Dynasty, Julu had been known as Nanyi County (南亦县). The name was changed and became Julu, with the Chinese for Ju being written either as either 巨 or 钜. In 1980, the name was standardized as 巨鹿.
