Prajñā (Buddhist monk)
Prajñā (, 734), was a 9th-century Buddhist monk born in Kapisa, near modern Kabul, Afghanistan. He visited Tang China and contributed several important retranslations of Sanskrit sutras into Chinese. Some of his main works are:

 The Avatamsaka Sutra ()
 The Heart Sutra ()
 The Mahayana Sutra of Mind Meditation from the Jataka tales ()

Prajñā reportedly befriended the Japanese monk Kūkai, future founder of Shingon Buddhism, during his pilgrimage to China. He is said to have helped Kūkai learn and understand Sanskrit source texts. According to the Zhenyuan Catalogue, Prajñā translated a work known as the Satparamita Sutra into Chinese with the help of the Christian monk Jingjing. This work does not survive. See also
