Sanlun or literally Three Treatise School was a Chinese school of Buddhism based upon the Indian Madhyamaka tradition, founded by Nagarjuna. The name derives from the fact that three principal Madhyamikan texts were translated by Kumarajiva to form the basis for the tradition.

Chi-tsang was a famous Sanlun disciple.

In 625, the Korean monk Ekwan brought the Sanlun school to Japan, where it was known as Sanron.
