Prajñā [alt. Prajña] (C. bore; J. hannya; K. panya 般若) was a Buddhist monk from northwest India who traveled to the Chinese capital of Chang'an in the ninth century (during the Tang dynasty).
He is best known for translating the Gandavyuha, the final chapter of the Avatamsaka Sutra. "Five other translations are also attributed to Prajna and his collaborators."
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.
