Luyi County (simplified Chinese: 鹿邑县; traditional Chinese: 鹿邑縣; pinyin: Lùyì Xiàn) is a county of eastern Henan, People's Republic of China, bordering Anhui province to the east.

[3][4][5] According to Sima Qian's Records of the Grand Historian, the village of Quren (曲仁里, Qūrén lǐ) in Li township (厲鄉, Lì xiāng) in Chu's Ku County (苦縣, Kǔ xiàn) was the birthplace of the legendary philosopher Laozi.

During the Song dynasty the Taiqing Palace was built in Luyi, an important Taoist shrine.

Although it only exists as ruins nowadays, it remains an important religious and archeological site.

[7][8] According to some historians, the Battle of Gaixia took place in what is now Luyi County.
