Daoxuan (Chinese: 道宣; pinyin: Dàoxuān; Wade–Giles: Tao-hsüan; 596–667) was an eminent Tang dynasty Chinese Buddhist monk. He is perhaps best known as the patriarch of the four-part Vinaya school (Chinese: 四分律宗). Daoxuan wrote both the Continued Biographies of Eminent Monks (Xù gāosēng zhuàn 續高僧傳 ) and the Standard Design for Buddhist Temple Construction. Legends retold in his biographies also associate him to a relic of the Buddha which came to be called Daoxuan's tooth (Daoxuan foya 道宣佛牙), one of the four tooth relics enshrined in the capital of Chang'an during the Tang dynasty. He is said to have received the relic from Nezha (Chinese: 那吒; Sanskrit: Naṭa), a divinity associated with Indra.
Daoxuan wrote five commentaries on the four-part Vinaya known as the Five Great Works of Mount Zhongnan. He was also part of the translation team that assisted Xuanzang in translating sutras from Sanskrit into Chinese.
