Faxian (337 - c. 422) was a Chinese Buddhist monk and translator who traveled by foot from Ancient China to Ancient India, visiting many sacred Buddhist sites in Central Asia, the Indian subcontinent and Southeast Asia between 399-412 to acquire Buddhist texts. His journey is described in his important travelogue, A Record of Buddhist Kingdoms, Being an Account by the Chinese Monk Fa-Xian of his Travels in India and Ceylon in Search of the Buddhist Books of Discipline. Other transliterations of his name include Fa-Hien, and Fa-hsien.

In 399 Faxian set out with nine others to locate sacred Buddhist texts. He visited India in the early fifth century. He is said to have walked all the way from China across the icy desert and rugged mountain passes. He entered India from the northwest and reached Pataliputra. He took back with him Buddhist texts and images sacred to Buddhism. He saw the ruins of the city when he reached Pataliputra.

Faxian's visit to India occurred during the reign of Chandragupta II. He is also renowned for his pilgrimage to Lumbini, the birthplace of Gautama Buddha (modern Nepal). However, he mentioned nothing about Guptas. Faxian claimed that demons and dragons were the original inhabitants of Sri Lanka.

On Faxian's way back to China, after a two-year stay in Ceylon, a violent storm drove his ship onto an island, probably Java. After five months there, Faxian took another ship for southern China; but, again, it was blown off course and he ended up landing at Mount Lao in what is now Shandong in northern China, 30 kilometres (19 mi) east of the city of Qingdao. He spent the rest of his life translating and editing the scriptures he had collected.

Faxian wrote a book on his travels, filled with accounts of early Buddhism, and the geography and history of numerous countries along the Silk Road as they were, at the turn of the 5th century CE. He wrote about cities like Taxila Patliputra, Mathura, and Kannauj in Middle India. He also wrote that inhabitants of Middle India also eat and dress like Chinese people. He declared Patliputra as a very prosperous city.

He returned in 412 and settled in what is now Nanjing. In 414 he wrote (or dictated) Foguoji (A Record of Buddhistic Kingdoms; also known as Faxian's Account). He spent the next decade, until his death, translating the Buddhist sutra he had brought with him from India.
